The correct option is (D)

<h3>What is a function?</h3>

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

the complete question is attached below

As, per the data given we can say that

the variation of quantity is 2.

So, the equation can be

y=2x

This equation defined by part (4) of the question.

A company offers premium cable for 39.95 per month plus a one time setup fee. the total cost for setup and 6 monthes of service

Yakvenalex [24]

Answer:

Part a) The equation of the line in point slope form is

$y-264.70=39.95(x-6)$

Part b) The equation in slope intercept form is

$y=39.95x+25$

Part c) The setup fee is $25

Step-by-step explanation:

Part a) write an equation in point slope form

Let

x ------> the number of months of service

y -----> the total cost

we know that

The equation of the line in point slope form is

$y-y1=m(x-x1)$

where

m is the slope

(x1,y1) is a point that lie on the line

In this problem we have that the cost of $39.95 per month is equal to the rate or slope of the linear equation

$m=39.95\ \frac{\$}{month}$

we have that the point (6,264.70) is a solution of the linear equation

substitute the given values

$y-264.70=39.95(x-6)$ ----> equation in point slope form

Part b) write the equation in slope intercept form

The equation of the line on slope intercept form is

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

we have

$y-264.70=39.95(x-6)$

Isolate the variable y

Distribute right side

$y-264.70=39.95x-239.70$

Adds 264.70 both sides

$y=39.95x-239.70+264.70$

$y=39.95x+25$

Part c) what is the setup fee?

The setup fee is the y-intercept of the linear equation

The y-intercept is the value of y when the value of x is equal to zero

In this problem, the y-intercept is the total cost when the number of months of service is equal to zero (the cost is equal to the setup fee)

For x=0

$y=39.95(0)+25$

$y=\$25$

The setup fee is $25

A store sells a package of 25 trading hearts for $5.25 use pencil and paper explain how you can tell that the unit price per car

creativ13 [48]

Answer:

Unitary cost per card= $0.21

Step-by-step explanation:

Giving the following information:

Number of cards per packecge= 25

Total cost per package= $5.25

<u>To calculate the unitary cost of each card, we need to use the following formula:</u>

Unitary cost per card= total cost / number of cards per package

Unitary cost per card= 5.25 / 25

Unitary cost per card= $0.21

Shane bought lunch for $5.38 and a shirt for $15.95. He then used the rest of his money to buy a book. He spent a total of $38.1

vovangra [49]

Sense the total would only be $38.12, we would then only want to find out how much would the book be, and that would be it. We would then want to add both how much the shirt and also the lunch was in total, and by doing this, we would the have to subtract this amount from the total that Shane has spent in total.

$\boxed{5.38+15.95 = 21.33 \ \sf(the \ amount \ of \ both \ lunch \ and \ shirt)}$

As we noted above, we then subtract both this total, and the amount that Shane has spent in this day.

$\boxed{38.12-21.33 = \bf{16.79} \Leftarrow \ (the \ cost \ of \ book)}$

Your answer: The book that Shane has purchased was a total of only 16.79.

16.79 would be your answer.
