p is 9
<u>Step-by-step explanation:</u>

Given 77 = 8p + 5. Find p
⇒ 8p + 5 = 77
⇒ 8p = 72
⇒ p = 72/8 = 9
A function is for every input, there is 1 output
aka
x never repeats with a different y
A. x doesn't repeat, it's a function
B. -8 repeats with 34 and 40, this is not a funciton (this is the answer0
C. x doesn't repeat, it's a function
D. x doesn't repeat, it's a function
answer is B
1) -2 + (-2) = 1.2p + 1/4p
2) -4 = 1.2p + 0.25p
3) -4 = 1.45p
4) -4/1.45 = p
