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

when g = 6

Find:

Value of equation

Computation:

5g + 7g + g(5 + 7)

5g + 7g + g(12)

5(6) + 7(6) + (6)(12)

Solve for x in the diagram
Aliun [14]

Answer:

x=12

Step-by-step explanation:

The two angles shown are complementary angles, so the add to 90 degrees

x+42 + 3x = 90

Combine like terms

4x+42 = 90

Subtract 42 from each side

4x+42-42 = 90-42

4x = 48

Divide by 4

4x/4 = 48/4

x = 12

olga55 [171]

Answer:

slope: 0 y-int: 6

Step-by-step explanation:

Horizontal lines ALWAYS have a slope of 0! Their y intercept is the y value they're always at, or the y value of the equation of their line. Looking at the graph, you can see that it's at 6.
