Answer:
A not similar
Step-by-step explanation:
72 × 2 = 144
78 × 2 = 156
For this problem, you need to substitute 4 in for your variable t. the original equation is S(t) and the one you need is S(4) -- in other words, evaluate this equation when t = 4.
S(4) = 9(4) - 4
S(4) = 36 - 4
S(4) = 32 is your answer.
Yes, because every x-value corresponds to exactly one y-value
