Two line painting trucks are painting lines on the side of a roadway. One truck painted 24 miles in 3 hours. The other truck painted 20 miles in 4 hours. Which ratio

Step-by-step explanation:

Given

Truck A

Truck B

Required

Determine the ratio of their speeds

Speed is calculated as:

For A:

For B:

So, the ratio is:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
