75 miles/hour
B.
80 miles/hour
C.
85 miles/hour
D.
90 miles/hour

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours

wait this depends wether emily and zach how they are thinking.

yes they are the same.
