Answer:
3 is yes, the rest is no
Step-by-step explanation:
for y = -6x - 9
(1) if x = 7, y = -51 => No
(2) if x = 3, y = -27 => No
(3) if x = -8, y = 39 => Yes
(4) if x = -5, y = 21 => No
3x - 2 = 13
Add 2 on both sides
3x - 2 + 2 = 13 + 2
3x = 13 + 2
3x = 15
Divide both sides by 3.
3x/3 = 15/3
x = 15/3
x = 5
Your final answer is A. 5.
