The P - intercept of the equation is 28

<em><u>Solution:</u></em>

Given equation models the relation between amount of Randy's monthly water bill payment and number of units of water used

P = 28 + 2.54w

Where,

"P" is the monthly water bill payment in dollars

"w" is the number of units of water used

Compare this equation with slope intercept form

Slope intercept form: y = mx + c

Where "m" is the slope of line and "c" is the y intercept

Therefore in given equation, P = 28 + 2.54w

2.54 is the slope and 28 is the P - intercept

The slope, 2.54, means that Randy’s payment increases by $2.54 when the number of units of water he used increases by 1

When "w" increases by 1 , then P increases by $ 2.54

The P –intercept means that if the number units of water Randy used was 0, the payment would be $28

When w = 0 ,

P = 28 + 0

P = $ 28

Thus the P - intercept determines the monthly payment bill

ElenaW [278]
The area of the square can be found by...
0.75 • 0.75 = .5625

The area of one triangle can be found by...
1/2 • 0.8 • 0.75 = .3

In order to find the total surface area of the figure, you must...
.5625 + 4(.3) = 1.7625

So the answer is D

Question # 55

We can see the trend from the given graph. From Monday to Thursday the price kept on decreasing while on Friday it increased. So first the price decreased and then increased.

Therefore, the correct answer to this question is option C. The price decreased at the beginning of the week and then increased at the end of the week.

Question # 56.

The schedule of athlete allows no more than 75 minutes of training. This means the training time is 75 minutes or less. One round of strength training requires 8 minutes. So s rounds of strength training will require 8s minutes. One round of endurance training require 12 minutes, so e rounds of endurance training will require 12e minutes.

The total time of both these trainings can be written as:

8s + 12e

We know that the time can be 75 minutes or lesser. So we can write the inequality as:

8s + 12e ≤ 75

So, option H is the correct answer

Question 57

The given equation is:

2y = - 3(x - 2)

In order to identify the slope we need to write the equation if slope intercept form. When written in slope intercept form, the coefficient of x term is the slope of the line. In order to write in slope intercept form, isolate y on one side as shown below:

2y=-3(x-2) \\  \\ &#10;2y=-3x+6 \\  \\ &#10;y=- \frac{3}{2}x+3

So, the slope of line is -3/2.

Hence option B is the correct answer
