Answer:

  • 12.5

Step-by-step explanation:

<u>This is a proportional relationship:</u>

  • y = kx

<u>Use a pair of values to find the coefficient of proportionality (5, 2.5):</u>

  • 2.5 = 5k
  • k = 2.5/5 = 0.5

k = 0.5 units represents a cost of a text message.

<u>25 text messages cost:</u>

  • 25*0.5 = 12.5 units

Library Fines for Overdue Books

Days overdue

Amount of fine

0

0 ¢

2

5 ¢

4

10 ¢

6

15 ¢

8

20 ¢

10

25 ¢

Which equation best models the fine schedule for overdue books?

y = five-halves x, where x is the cost in cents for a book that is y days overdue

y = five-halves x, where y is the cost in cents for a book that is x days overdue

y = 5 x, where x is the cost in cents for a book that is y days overdue

y = 5 x, where y is the cost in cents for a book that is x days overdue

SOMEONE PLSSSS HELP!!! Explain the difference in the graphs of Car #1 and Car #2. What is the Slope of each? Why is one line ste
dusya [7]

Answer:

Car 1 slope = 35

Car 2 slope = 40

Red line(car 2) is steeper than the blue line(car 1)

slope is miles per gallon

Step-by-step explanation:

Slope formula is

slope = \frac{y_2-y_1}{x_2-x_1}

To find slope, pick two points from graph of Car 1

(4,140) (6,210)

slope Car1= \frac{210-140}{6-4}= 35

To find slope, pick two points from graph of Car 2

(3,120) (5,200)

slope Car 2= \frac{200-120}{5-3}= 40

When slope is larger then line is steeper

slope of Car 2 is greater than slope of Car1

So Red line is steeper than the blue line.

Slope is change is y over change in x

It means Change in miles over change in gallons

So slope is miles per gallon
