Marnie drove 150 miles in 2 hours. The distance Marnie drives, , is a function of the time Marni e spends driving, . Assume Marnie was driving at a constant rate. 1. The equation that represents her distance driving as a function of the amount of time is:

2. After 4 hours, Marnie was driving for
miles.

3. After 9 hours, Marnie drove
miles.

4. If we were to plot the points from exercises 2 and 3, we would find out that the function is a
function.

(x, y)→(x − 8, y − 7)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
