step-by-step explanation:
u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
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.
