Answer:

8 pounds

Step-by-step explanation:

Shipping Company A = 14 + 2.25p

Shipping Company B = 20 + 1.50p

Where,

p = the number of pounds.

For what weight is the charge the same for the two companies

Equate the charges of the two companies

14 + 2.25p = 20 + 1.50p

14 - 20 = 1.50p - 2.25p

-6 = -0.75p

Divide both sides by -0.75

p = -6 / -0.75

= 8

p = 8 pounds

Answer:

Step-by-step explanation:

The price per ounce for the 8-ounce jar is ...

  price/ounces = $8.95/8 = $1.11875 ≈ $1.12 . . . per ounce

The price per ounce for the 10-ounce jar is ...

  $12.00/10 = $1.20 . . . per ounce

The 8-ounce jar has a lower unit price, so may be better to buy.*

__

The difference in unit prices is ...

  $1.20 -1.12 = $0.08

_____

* If you need at most 10 ounces, but more than 8, the 10-ounce jar will have a lower total cost for the amount needed. The "better buy" depends on the context.

Answer:

  10. (x, y) = (-3/8, 2 9/16)

  11. k = -1

Step-by-step explanation:

10. The value of x at the vertex is ...

  x = -b/(2a)

  x = -(-3)/(2(-4)) = -3/8

The corresponding value of y is ...

  y = 2 +(-3/8)(-3 +(-3/8)(-4)) = 2 +(-3/8)(-3/2) = 2 +(9/16)

The vertex is (x, y) = (-3/8, 2 9/16).

__

11. The discriminant is zero when the roots are equal.

  b² -4ac = 0

  (k-1)² -4(1)(-k) = 0

  k² -2k +1 +4k = 0

  k² +2k +1 = 0 . . . . . collect terms

  (k +1)² = 0 . . . . . . . . write as a square

  k = -1 . . . . . . . . . . . . the value of k that satisfies

  x² -2x +1 = (x -1)² = 0 . . . . has equal roots: x=1.

Answer:

Seth saved $90.

Step-by-step explanation:

1.Find out how much would be spent without buying the movie pass.

Multiply the amount of money that one would spend for each movie, by the number of movies one saw.

8 * 30 = 240

2.Find out the amount that was actually spent

Multiply the amount that was actually spent on each movie, by the number of movies that were seen. Then add the additional cost of the pass.

(4 * 30) + 30

= 120 + 30

= 150

3. Find the difference between the two values.

Subtract the amount that one was supposed to spend by the amount one did spend.

240 - 150

= 90

Answer:

26.25 = x

Step-by-step explanation:

f ( x ) = 4x - 5

f  ( x ) = Y-value

x = x - value

If f ( 100 ) = The Y is 100

100 = 4x - 5

+5   =      +5                    Add 5 on both sides. The 5's will cancel on the right

-------------------

105 = 4x                 Divide by 4 on both sides. The 4's will cancel on the right

----- =  ----

4     =  4

26.25 = x

Hope this helps!!

Answer:

105

Step-by-step explanation:

First, you are going to convert dollars to cents. Since there are 100 cents in a dollar, multiple $20 by 100. Now you should have 2,000 cents. Now all you have to do is divide by 19, the cost of the stamps, and you should get 105.26. Because you can't by part of a stamp your answer would be 105.

Option C is the correct option.

Step-by-step explanation:

A set of equations is given below:

Equation H: y = -x + 2

Equation J: y = 3x - 4

We need to determine the step to solve the equations.

We can place value of y from Equation H into Equation J

i.e

-x+2=3x-4

So, Option C is the correct option.

Answer:

The domain of relation is {1,3,5}

It is not a function.

Step-by-step explanation:

Given the relation {(1, 4), (3, 6), (5, 4), (1, 8)}

We need to find the domain and determine if the given relation is function or not.

The domain of relation is {1,3,5}

But the given relation is not function because we have x=1 twice in the relation and the for the relation to be function the values of domain can't be repeated.

So, It is not a function.

r = rate of change

t = time

A = B(1 + r)^t

2245(1 + 0.017)^5 = 2442.42428756

2442.42428756 = 2442.42

Answer:

Step-by-step explanation:

Whether a prdocut will be positive or negative really depends on the signs of the two numbers being multiplied.

In other words,

(positive number) × (positive number) = positive number

(negative number) × (negative number) = positive number

For example, when we multiply the positive numbers 3 and 4, the product will be positive.

i.e. 3 × 4 = 12

Also, when we multiply the negative numbers 3 and 4, the product will again be positive.

i.e. (-3) × (-4) = 12

(positive number) × (negative number) = negative number

For example, when we multiply the positive number 3 and negative number -4, the product will be negative.

i.e. (3) × (-4) = -12

I hope your concept is clear now.

lcm of 6 and 3 is 6

Therefore 6 thank you cards and 6 birthday cards were sold

Answer:

88%

Step-by-step explanation:

From the question given above, the following data were obtained:

Original amount = $ 90

Discounted amount = $ 79.20

Percentage of discount =?

Let the percentage of discount be y %

Thus, we can obtain the value of y as follow:

y /100 × 90 = 79.20

90y /100 = 79.20

Cross multiply

90y = 100 × 79.20

90y = 7920

Divide both side by 90

y = 7920/90

y = 88

Thus, the percentage discount of the blender is 88%

Pythagorean theorem

Answer:

(2,0)

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

2x+y=4; x−y=2

Step: Solve 2x+y = 4 for y:

2x + y + −2x = 4 + −2x (Add -2x to both sides)

y = −2x+4

Step: Substitute −2x+4 for y in x−y=2:

x − y=2

x−(−2x + 4)=2

3x − 4=2(Simplify both sides of the equation)

3x − 4 + 4 = 2+4 (Add 4 to both sides)

3x =6

(Divide both sides by 3)

x=2

Step: Substitute2forxiny=−2x+4:

y= −2x + 4

y=(−2)(2) + 4

y=0 (Simplify both sides of the equation)

Answer:

x=2 and y=0

The compound inequality that represent the situation is 2(x + 7) > 6 and 2(x + 7) ≤ -3.

Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.

Compound inequality is an inequality that combines two simple inequalities.

Therefore, let's represent twice the sum of a number and 7 is more than 6 or at most -3 with compound inequality as follows:

Therefore,

2(x + 7) > 6 and 2(x + 7) ≤ -3

8 ÷ 2 = 4

(x + 3)(x + 3) ÷ (x + 3) = (x + 3). In other words, we cancel one of the numerator factors.

Answer: 4(x + 3).

The simplification of the given expression [8(x+3)²]/[2(x+3)] is 4(x + 3).
