A hardware store rents vacuum cleaners that customers may use for part or all of a day, up to 12 hours, before returning. The store charges a flat fee plus an hourly rate. Write a linear function f for the total rental cost of a vacuum cleaner. A. f(x) = 6x + 14
B. f(x) = 3x + 14
C. f(x) = 3x + 22
D. f(x) = 6x + 24

Flat fee the store charges =

A reasonable domain for the function is: =

Cost to rent a vacuum for 7 hours =

step-by-step explanation:

let

we know that

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

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

c

-by-step explanation:

it would be c

i think the answer would be c
