The equation y = 8.5x - 77.5 is a linear model for data comparing the
speed that a car is going (x) to the stopping distance it takes for the car to stop
(y). speed is measured in mph and distance in feet. what is the average
stopping distance of a car going 45 mph?

Step-by-step explanation:

The given equation is

Observe that the the ratio of change is 8.5 and the y-intercept is at (0, -77.5).

Where is the speed and is the distance.

So, to find the average stopping distance of a car going at 45 mph, we just replace this value in the given equation

Therefore, the distance is 705 feet.

just keep asking questions until you have a better understanding.

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
