Given g(x)= -2x -7, find g(-3)

Question 9
9.

We have been using the formula D=rt all trimester to represent that distance traveled equals the rate (speed) multiplied by the time at that speed. You are traveling at a constant rate of 60 miles per hour. So your distance will be a function of your time. How far will you travel in 5 hours?

Question 10
10.

At a constant rate of 60 miles per hour, it is also fair to say that time is a function of your distance. So if you travel 600 miles, how long will it take?
