A hardware store rents vacuum cleaners that customers may use for part or all of a day, up to 12 hours, before returning. The st
jek_recluse [69]

The flat fee that the store charges is $14 and the cost for 7 hours is $56

A linear equation is on the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

let f for the total rental cost of a vacuum cleaner for x hours

Using the points (1, 20) and (3, 32) from the table:

f-f_1=\frac{f_2-f_1}{x_2-x_1} (x-x_1)\\\\f-20=\frac{32-20}{3-1} (x-1)\\\\f(x)=6x+14

The flat fee that the store charges is $14

The reasonable domain is 1 ≤ x ≤ 12

The cost for 7 hours is:

f(7) = 6(7) + 14 = 46

What is the answer for 34-54x
Brums [2.3K]

Answer:

2(17-27x)

Step-by-step explanation:

Since the question was incomplete this is the only answer I have for you.

If you were looking for the answer of X I would need a answer for the equation

Anyways... you want to factor out 2 from the expression since there are two numbers

Once you factored out the two (divide each number by 2) you'll get:

2(17-27x)
