solve using systems answer in a ordered pair
y = –x + 3
y = 4x – 2

Answers

Answer 1

Answer:

(1,2)

Step-by-step explanation:

Pre-Solving

We are given the following system of equations:

y = -x + 3

y = 4x - 2

And we want to solve it, with the answer in an ordered pair.

Solving

Because both systems are equal to y, we can set both of the equations equal to each other, and solve for x in that way.

This is possible due to transitivity, which states that if a=b, and b=c, then a=c.

Hence,

-x + 3 = 4x - 2 (same as y=y)

We can add x to both sides.

3 = 5x - 2

Add 2 to both sides.

5 = 5x

Divide both sides by 5.

1 = x

Now, we can use this value to find y.

Substitute 1 as x in either y = -x + 3 or y = 4x - 2

Taking y = -x + 3 for instance:

y = -1 + 3 = 2

So, we now that x=1, y=2.

As an ordered pair, that is (1,2).

• Can you stop checking for factor pairs when you find a pair

Answers

Yes, you can stop checking for factor pairs when you find a pair that repeats.

What are factor pair rules?

A factor pair is defined in mathematics as a set of two factors that, when multiplied together, produce a specific product. In other words, it is a set of two numbers that we multiply to get a product. For example, in the multiplication statement, 6 7 = 42, 6 and 7 is one of the factor pairs that gives us the product 42.

This is due to the fact that each number has a unique set of factors. When you find a factor pair that repeats, you know you've found all of the factors of that number. Any additional pairs you find will simply be a permutation of the same factors you've already discovered.

Consider the number 24 as an example. Its components are as follows:

1, 2, 3, 4, 6, 8, 12, 24

When looking for factor pairs, we begin with 1 and 24, then move on to 2 and 12, 3 and 8, and finally 4 and 6. We now have all of the factors of 24 because we discovered a pair (4, 6) that repeats the same factors as an earlier pair (6, 4).

As a result, once you find a pair of factors that repeats, you can be confident that you have discovered all of the factors of the number you are investigating.

The following graph represents the distance a commercial airplane travels over time, at cruising speed and an altitude of 35,000 feet. In fact, the distance the airplane travels at cruising speed is directly proportional to the time it travels. What is the cruising speed of the airplane? In your answer, use complete sentences to describe how you found the speed.

1,567 - 2,1134 - 3,1701 - 4, 2268 - 5,2268

Answers

By analyzing the relationship between the distance traveled and the time taken from the given graph, we determined that the cruising speed of the airplane is 567 units of distance per 1 unit of time.

To find the cruising speed of the airplane, we can analyze the given graph and observe the relationship between the distance traveled and the time taken.

Looking at the data points provided, we see that the distance traveled is directly proportional to the time taken. This means that for every unit increase in time, there is a corresponding increase in the distance traveled.

Let's consider the first two data points: (1,567) and (2,1134). The time difference between these two points is 2 - 1 = 1, and the distance traveled difference is 1134 - 567 = 567.

Since the distance traveled is directly proportional to time, we can conclude that the speed of the airplane is equal to the distance traveled divided by the time taken. In this case, the speed would be 567 units of distance per 1 unit of time.

Now, let's calculate the cruising speed using the other data points as well:

(2,1134) - (1,567) = 1134 - 567 = 567 units of distance per 1 unit of time

(3,1701) - (2,1134) = 1701 - 1134 = 567 units of distance per 1 unit of time

(4,2268) - (3,1701) = 2268 - 1701 = 567 units of distance per 1 unit of time

(5,2268) - (4,2268) = 2268 - 2268 = 0 units of distance per 1 unit of time

We can see that for each time interval, the distance traveled is always 567 units. Therefore, we can conclude that the cruising speed of the airplane is 567 units of distance per 1 unit of time.

The original price of each 6‑day ski pass is reduced by 15% in a sale. In the sale the price of each 6‑day ski pass is $272.
(a) Calculate the original price of each 6‑day ski pass. The price of each 3‑day ski pass is £110 The exchange rate is £1 = $1.70 .
(b) Calculate how much Andrew will save by buying one 6‑day ski pass in the sale rather than two 3‑day ski passes.​

Answers

Step-by-step explanation:

(a) Let the original price of each 6-day ski pass be x. Then, the sale price of each pass is 0.85x = 272. Solving for x, we have:

0.85x = 272

x = 320

Therefore, the original price of each 6-day ski pass was $320.

(b) Two 3-day ski passes cost 2 x £110 = £220. Converting to US dollars using the exchange rate, we have:

£220 x 1.70 = $374

Therefore, Andrew would save:

$374 - $272 = $102

by buying one 6-day ski pass in the sale rather than two 3-day ski passes.

Write the function in factored form. Check by multiplication.
y = - 4x³ - 16x² +84x
y= (Factor completely.)

Answers

Answer:

Step-by-step explanation:

We can factor out a common factor of -4x from the equation:

y = -4x(x² + 4x - 21)

To factor the quadratic expression in the parentheses, we need to find two numbers that multiply to -21 and add to 4. These numbers are 7 and -3:

y = -4x(x + 7)(x - 3)

To check our work, we can multiply the three factors:

y = -4x(x + 7)(x - 3) = -4x(x² + 4x - 21) = -4x³ - 16x² + 84x

So the factored form is y = -4x(x + 7)(x - 3), and the check shows that we have factored the equation correctly.

The sale of the 100th unit will decrease profit by |P(101) − P(100)| dollars.

Answers

R(x) = 47x denotes the total revenue function, and C(x) = 100 + 30x + 0.1x2 is the total cost function.

(a) P(100) = -200

(b) MP(x) = 47 - (30 + 0.2x)

(c) MP(100) = -3

(d) P(101) - P(100) = -0.2

(a) P(100) represents the profit made when x=100 units are sold. It can be calculated as follows:

P(x) = R(x) - C(x)

P(100) = R(100) - C(100)

P(100) = [tex]47(100) - (100 + 30(100) + 0.1(100)^2)[/tex]

P(100) = 4700 - 4000 - 100

P(100) = -200

(b) The marginal profit function MP represents the rate of change of profit with respect to the number of units sold. It can be calculated as follows:

MP(x) = R'(x) - C'(x)

MP(x) = 47 - (30 + 0.2x)

(c) MP(100) represents the marginal profit at x=100 units. It can be calculated by substituting x=100 into the marginal profit function:

MP(100) = 47 - (30 + 0.2(100))

MP(100) = 47 - 50

MP(100) = -3

Profit will drop by |MP(100)| dollars at x = 100, according to MP(100).

(d) P(101) - P(100) represents the additional profit made when the 101st unit is sold compared to when the 100th unit is sold. It can be calculated as follows:

P(101) - P(100) = R(101) - C(101) - R(100) + C(100)

P(101) - P(100) =[tex]47(101) - (100 + 30(101) + 0.1(101)^2) - 47(100) + (100 + 30(100) + 0.1(100)^2)[/tex]

P(101) - P(100) = 47 - 30 - 0.2(101) - 47 + 30 + 0.1(100)

P(101) - P(100) = -0.2

Step-by-step explanation:

The distribution of opinions on the legality of same-sex marriage worldwide is not described in the prompt, so it is not possible to determine the type of distribution. However, it is possible to use the proportions provided to estimate the number of Americans who felt that same-sex couples should be allowed to legally marry.

If 58% of all adults worldwide believe that same-sex marriage should be legal, and 1,280 adults were polled nationwide, we can estimate the number of Americans who hold this opinion as:

0.58 x 1,280 = 742.4

Alternate angles are created when two parallel lines are intersected by a transversal. Have a look at the given illustration; the two parallel lines are EF and GH. When a transversal splits two parallel lines, the alternate angles are equal.

The alternate interior angles are equal because of the parallel lines characteristic.

Angle STQ (denoted as 2x+10) and angle RQS are hence equal. Angle QRP (shown as x+20) and angle RQS are likewise equal.

A pension fund manager decides to invest a total of at most ​$40 million in U.S. Treasury bonds paying 6​% annual interest and in mutual funds paying ​8% annual interest. He plans to invest at least ​5$ million in bonds and at least 15​$ million in mutual funds. Bonds have an initial fee of​ $100 per million​ dollars, while the fee for mutual funds is​ $200 per million. The fund manager is allowed to spend no more than ​$7000 on fees. How much should be invested in each to maximize annual​ interest? What is the maximum annual​ interest?

The amount that should be invested in Treasury bonds is ​$___ million and the amount that should be invested in mutual funds is ​$__ million.

The maximum annual interest is ​$___

Answers

Answer:

Let x be the amount invested in Treasury bonds and y be the amount invested in mutual funds. Then we have the following constraints:

x + y ≤ 40 (total investment cannot exceed $40 million) x ≥ 5 (at least $5 million must be invested in Treasury bonds) y ≥ 15 (at least $15 million must be invested in mutual funds) 100x + 200y ≤ 7000 (total fees cannot exceed $7000)

The objective is to maximize the annual interest, which is given by:

0.06x + 0.08y

We can solve this problem using linear programming. The feasible region is a polygon with vertices at (5, 15), (5, 35), (30, 10), and (40, 0). We evaluate the objective function at each vertex:

At (5, 15): 0.06(5) + 0.08(15) = 1.2At (5, 35): 0.06(5) + 0.08(35) = 2.6At (30, 10): 0.06(30) + 0.08(10) = 2.8At (40, 0): 0.06(40) + 0.08(0) = 2.4

The maximum value of the objective function is 2.8, which occurs at (30, 10). Therefore, the amount that should be invested in Treasury bonds is $30 million and the amount that should be invested in mutual funds is $10 million.

The annual interest earned is 0.06(30) + 0.08(10) = $2.8 million.

IEEE-754 representation for float (single-precision) type is as follows

Sign - 0

Exponent - 1 to 18

Mantissa - 9 to 31

So the exponent field is 8 bits and the mantissa is 23 bits (the precision is actually 24 bits due to the implicit 1 needed in the normalized representation; IEEE 754 also allows demoralized numbers close to 0, but this does not does not apply to the particular question).

Exponential fields also require signs to represent fractions. IEEE 754 does this by giving a bias - 127 for single precision, which means we just subtract 127 from the suggested value to get the actual value. So 0 becomes -127 and 255 (the maximum 8-bit value becomes 128.

Now, coming to the given question we need to represent -14.25 which equals -1110.01 in binary.

Converting to normalized form (only one to the left ) we get

-11101.01 =-1.11001 × 2³

Since we omit the implied  in IEEE-754 representation we get

Mantissa bits = 11001

Exponent bits = 11 + 0111111 = 10000010 (Adding bias Sign bit 1)

Define the conditional statement for contrapositive?

The contrapositive of a conditional statement is a new conditional statement that is formed by negating both the hypothesis (the "if" part) and the conclusion (the "then" part) of the original statement, and switching their positions. The truth table for the contrapositive of a conditional statement has the same number of rows as the truth table for the original statement.

For example, if the original statement is "If it is raining, then the ground is wet", then the contrapositive would be "If the ground is not wet, then it is not raining."

Joy Milne of Perth, UK, smelled a "subtle musky odor" on her husband Les that she had never smelled before. At first, Joy
thought maybe the smell was from Les's sweat after long hours of work. But when Les was diagnosed with Parkinson's 6 years
later, Joy suspected the odor might be a result of the disease. Scientists were intrigued by Joy's claim and designed an
experiment to test her ability to "smell Parkinson's." Joy was presented with 12 shirts, each worn by a different person, some of
whom had Parkinson's and some of whom did not. The shirts were given to Joy in random order, and she had to decide whether
each shirt was worn by a Parkinson's patient or not. Joy identified 11 of the 12 shirts correctly. If we assume that Joy was just
guessing, she would have probability 1/2 of correctly identifying each shirt.
(a) Find the probability that Joy would identify at least 11 shirts correctly by random guessing.

What is Probability?

The ratio of favaourable outcomes to all possible outcomes of an event is known as the probability. The total number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence can be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

The profit (in thousands of dollars) from the expenditure of x thousand dollars on advertising is given by P(x)=1000+32x-2x2. Find the marginal profit at the following expenditures.

Answers

The marginal profit at the following expenditures for $8000 is 0 for $6000 is 8 for $12,000 is -16 and for $20,000 is -48.

When one more unit is produced and sold, a company or individual will make a profit known as marginal profit. The additional expense or profit made while manufacturing the next unit is referred to be marginal. Whereas marginal cost is the additional expense for manufacturing one extra unit, marginal product is the additional income received.

The difference between marginal cost and marginal product is known as marginal profit (also known as marginal revenue). Managers can utilise margin analysis to help them decide whether to increase output, reduce production, or halt production completely, a decision known as the shutdown point.

we have,

P(x)= 1000+32x - 2x²

Formula for derivative of function:

[tex]f'(x) = \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex]

Finding the derivative,

P(x+h) = 1000 + 32(x+h) - 2(x+h)²

P(x+h) = -2x² -4xh - 2h² + 32x + 32h + 1000

P(x+h) - P(x) = h(-4x - 2h + 32)

P'(x) = -4x + 32

Finding derivatives for given values of x is,

P'(8) = -4(8) + 32 = 0

P'(6) = -4(6) + 32 = 8

P'(12) = -4(12) + 32 = -16

P'(20) = -4(20) + 32 = -48

Anne, Boris, and Carl ran a race. They started at the same time, and their speeds were constant. When Anne finished, Boris had 15 m to run, and Carl had 35 m to run. When Boris finished, Carl had 22 m to run. What is the distance they ran?

Answers

The distance they ran is [tex]b * t1^2 * (d - 35) + 15 * t1 = 13t1.[/tex]

In math, what is a distance?

The length οf the line segment cοnnecting the twο sites is used tο measure distance between them. The shοrtest line segment between a pοint and a line will have a length equal tο the distance between them.

With the data abοve, we can create twο equatiοns using the fοrmula distance = speed x time:

Equatiοn 1: (d - 15) = b * t1

Equatiοn 2: (d - 35) = c * t1

Where t1 is the amοunt οf time it tοοk Anne tο cοmplete the race.

Carl cοvered a distance οf d - 22 after Bοris had dοne his 22 m οf running. The same fοrmula can be used tο create a different equatiοn:

Equatiοn 3: (d - 22) = c * t2

where t2 is the amοunt οf time it tοοk Bοris tο cοmplete the race.

Equatiοns 1 and 2 can be used tο find b and c in terms οf t1:

b = (d - 15) / t1

c = (d - 35) / t1

Substituting these equatiοns intο Equatiοn 3, we get:

(d - 22) = (d - 35) / t1 * t2

Simplifying, we get:

t1 * t2 = 13 / c

In the previοus equatiοn, we may substitute the fοrmulas fοr b and c in terms οf t1 tο οbtain:

t1 * t2 = 13t1 / (d - 35)

Simplifying, we get:

t2 = 13 / (d - 35)

Tο sοlve fοr b in terms οf t1, we can insert the fοllοwing fοrmula fοr t2 intο Equatiοn 1:

(d - 15) = b * t1

(d - 15) = ((d - 35) / t1) * 13 / (d - 35) * t1

Simplifying, we get:

b = 13 / t1 - 2

Substituting this expressiοn fοr b intο Equatiοn 2, we get:

(d - 35) = c * t1

(d - 35) = ((d - 15) / t1 - 13 / t1 + 2) * t1

Simplifying, we get:

c = (d - 35) / t1 + 13 / t1 - 2

Nοw we can create anοther equatiοn using these expressiοns fοr b and c in terms οf t1:

d = (d - 15) + 15 = b * t1 + 15

d = (d - 22) + 22 = c * t2 + 22 = (d - 35) / t1 * 13 / (d - 35) + 22

When we equalize these twο expressiοns, we οbtain:

b * t1 + 15 = (d - 35) / t1 * 13 / (d - 35) + 22

Multiplying bοth sides by t1 * (d - 35), we get:

b * t1² * (d - 35) + 15 * t1 * (d - 35) = 13t1² + 22t1 * (d - 35)

Simplifying, we get:

b * t1² * (d - 35) + 15 * t1 = 13t1

x
? A. 1 B. 2 C. 3 D. 4 E. 5

Answers

If x is an integer, the least possible value of x is 4. So the option D is correct.

The triangle's third side should be less than the sum of the other two sides and more than the difference of the other two sides.

11 - 7.5 < x < 11 + 7.5

Simplify

3.5 < x < 18.5

So the value of the x is between 3.5 and 18.5.

From the option the value 4 and 5 lies between 3.5 and 18.5.

As we have to determine the least possible value of x, so the value of x should be 4. So the option D is correct.

Samir bought three pounds of strawberries for $12.00. What is the price, in dollars
per ounce of strawberries?
1 pound = 16 ounces
Before you try that problem, answer the question below.
How many ounces of strawberries did Samir buy?

Answers

Samir bought 48 ounces of strawberries (3 pounds x 16 ounces per pound = 48 ounces).
To find the price per ounce, we can divide the total cost by the number of ounces:
$12.00 ÷ 48 ounces = $0.25 per ounce.
Therefore, Samir paid $0.25 for each ounce of strawberries he bought.

find the volume of a frustum of a pyramid with square base of side 27, square top of side 15 and height 10.

Answers

The volume of the frustum of the pyramid is 4530 cubic units.

To find the volume of a frustum of a pyramid, we can use the formula

V = (1/3)h(A1 + A2 + sqrt(A1A2))

Where

V is the volume of the frustum.

h is the height of the frustum.

A1 is the area of the base of the frustum.

A2 is the area of the top of the frustum.

In this case, the frustum has a square base of side 27 and a square top of side 15. Therefore, we have

A1 = 27^2 = 729

A2 = 15^2 = 225

h = 10

Now we can plug these values into the formula

V = (1/3)10(729 + 225 + sqrt(729*225))

V = (1/3)10(954 + sqrt(164025))

V = (1/3)10(954 + 405)

V = (1/3)10(1359)

V = 4530 cubic units

The base of the triangle is decreasing at a rate of 36/19 cm/min when the altitude is 9.5 cm and the area is 94 sq cm.

What does calculus' chain rule mean?

We can differentiate composite functions using the chain rule in calculus. Any function that is created by fusing two or more other functions is referred to as a composite function. According to the chain rule, if y = f(g(x)), and f and g are both differentiable functions, then the derivative of y with respect to x is given by:

dy/dx = f'(g(x)) * g'(x)

Given that, the altitude is 9.5 cm and the area is 94 sq cm.

The area of the triangle is given as:

A = 1/2(b)(h)

Differentiating both sides with respect to time we have:

dA/dt = 1/2[(db/dt)(h) + b(dh/dt)

Now,

dA/dt = 2 and dh/dt = 2.

Substituting the values we have:

2 = (1/2) * (db/dt * 9.5 + b * 2)

4 = db/dt * 9.5 + 2b......(1)

Using the area of triangle we know that:

Area = (1/2) * b * h

94 = (1/2) * b * 9.5

b = 20

Substituting the value of b in equation 1 we have:

4 = db/dt * 9.5 + 40

db/dt = - 36/19 cm/min

Hence, the base of the triangle is decreasing at a rate of 36/19 cm/min when the altitude is 9.5 cm and the area is 94 sq cm.
