P = 3(x - 4.5) ← as a product

Answer:

c

Step-by-step explanation:

Given the2 equations

y = x + 4 → (1)

x + y = 2 → (2)

Substitute y = x + 4 into (2)

x+ x + 4 = 2

2x + 4 = 2 ( subtract 4 from both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

Substitute x = - 1 into (1) for corresponding value of y

y = - 1 + 4 = 3

solution is (- 1, 3 ) → c

Step-by-step explanation:

Answer:

The figure would move 2 units to the left and 4 units up and the image would be congruent.

Step-by-step explanation:

If you transformed a figure using the rule (x-2, y+4).

Then the figure would move 2 units to the left (x-2) and 4 units up (x+4).

Similar figures would have the same shapes but different sizes.

Congruent figures would have the same shapes and same sizes but might be rotated.

Figures can not be both similar and congruent.

Moving the whole shape will not change the size; therefore, the figures would be congruent.

Answer:

D. x2 = 52 + 32 – 2(5)(3)cos(140°)

Step-by-step explanation:

The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°). Option B is corect.

Distance is a numerical representation of the distance between two objects or locations.

The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.

Distance is measured in the meter, centimeter, miles, nautical mile, feet, etc. The unit of distance is most important to find it.

The distance, x, from the starting point is;

From the cos law ;

x² = a² +b²-2ab cosΘ

From the digrame it is obtained that;

a =5

b =3

Θ = 180 ° +70° -30°

Θ = 180°- 40°

Θ = 140°

Substitute the values;

x² = a² +b²-2ab cosΘ

x²=5²+3²-2(5)(3)cos(140°)

The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°).

Hence option B is corect.

Find an ordered pair to represent in the equation vec t = 4 vec u +6 vec v where vec u =(-1,4) and vec v = (3,-2)

Substitute the given vector into the expression for vec t.

Recall that: vec t = 4 vec u +6 vec v

vec t = 4(-1,4)+6(3,-2)

vec t = (4(-1), 4(4)) + (6(3), 6(-2))

vec t = (-4, 16) + (18, -12)

vec t = (-4+18, 16+(-12))

vec t = (14, 16-12)

vec t = (14, 4)

Hence an ordered pair to represent vec t in the equation is (14, 4)

Note that the vec v was assumed. Any other vector coordinate can also be used

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

To find the slope of a line, we would need to use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex]. These points can be any two points that fall on the line.

In the graph, two points we can use to find the slope is (1, 2) and (-2, 0).

[tex]\frac{y_2-y_1}{x_2-x_1}\\\\\frac{0-2}{-2-1} \\= \frac{-2}{-3} \\= \frac{2}{3}[/tex]

Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

Answer:

8.33%

Step-by-step explanation:

We are told to:

Express the first quantity as a percentage of the second

a. 80cents of $9.60

The first quantity is 80 cents, the second quantity is $9.60

Step 1

We convert 80 cents to a dollar

100 cents = $1

80 cents = $x

$x = 80/100 = $0.8

Step 2

We express $0.8 as a percentage of $9.60

Hence, we have:

$0.8/$9.60 × 100

= 8.33%

Answer:

24

Step-by-step explanation:

Corey has saved an amount of 24 dollars, if they have saved up a total of $78.00.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's assume that Corey has saved an amount of x dollars.

Given that Jasper and Corey have saved up a total of $78.00.

Jasper has saved 6 dollars more than twice as much as

Corey.

As per the given condition, the algebraic form is:

(6 + 2x) + x = 78.  

Rearrange the terms of variables of x in the above equation,

6 + 2x + x = 78

Apply the addition operation,

6 + 3x = 78

Subtract 6 from both sides in the equation,

3x = 72

Now divide both sides by 3 in the equation,

x = 24

Therefore, Corey has saved an amount of 24 dollars.

Answer:

The percentage of people who are satisfied with this car model is 30%.

Step-by-step explanation:

Given that the survey interviewed 1,900 people who own a certain type of car, and of them 570 said that they would buy the same car model again, to determine the percentage of people who are satisfied with that model it is necessary to perform the following calculation :

1,900 = 100

570 = X

((570 x 100) / 1,900) = X

57,000 / 1,900 = X

30 = X

Therefore, the percentage of people who are satisfied with this car model is 30%.

Answer:

Jazmine will pay only $40 for both discounts.

Step-by-step explanation:

First we need to add the two discounts, 35% + 25% = 60%.

Now we need to convert 60% into a decimal, which is 0.60.

Now we need to multiply the regular price, $100, by 0.60.

$0.60 × $100 = $60.

Now we subtract the discount by the amount, $100 - $60 = $40.

Answer:

The probability that there is at least one pair but not a three of a kind is 0.6944.

Step-by-step explanation:

We have the case when we have five dices and we roll them and we need  that there is at least one pair but not a three of a king which is Two dice showing the same value, but no three dice showing the value.

Total no of outcomes = [tex]6^5 = 7776[/tex]

We will consider the other cases and then subtract them from the total outcomes.

No of outcomes of 5 of a kind = 6

No of outcomes 4 of a kind and 1 different = (6*5)*5 = 150

No of outcomes with 3 of a kind and 1 different pairs = (6*1*1*5*1)*5C2= 300

No of outcomes with 3 of a kind and two different = 6*5*4*10= 120*10=1200

No of outcomes when all are different = 6! = 720

These all the cases when subtracted from the total will represent the total cases in which there are two dice showing the same value.

Total cases = 6+150+300+1200+720

                   = 2376

Required no of outcomes = 7776-2376 = 5400

Probability = [tex]\frac{5400}{7776}[/tex] = 0.6944

Therefore the probability for the case of at least one pair but not a three of a kind is 0.6944.
