Oof retest because last one I mixed up

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.

15 / 2 = 7.5

100 / 7.5 = 13.

turn 2 ft into 24 inches. then divide both numbers by 6 getting you 4 and 9. now make the fraction have a numerator of 4 and a denominator of 9, the answer is 4/9.
