Answer:
D.
Step-by-step explanation:
-2x-1 =y
-2x 2= -4-1
= -5
=2, -5
Y=35x+50 bc you already have to pay 50$ and then you spend 35 a hour and the X represents how many hours.
2(7/2)^x = 49/2
Divide both sides by 2:
(7/2)^x = 49/4
I notice that 49/4 can be rewritten as (7/2)^2, so we now have:
(7/2)^x = (7/2)^2
The only way for this to be true is if x = 2. Thus, we are done.
