If you are trying to find the area the answer would be 48
I might be wrong but don’t you need two equations to do the elimination process?
1. C
2. B
Good luck with the rest
A.9×6x - ( 9×2)=
64x-18 = 0
64x=18
x=18/64 =1/3 =0.3
B. 64x+18=0
64x= -18
x =-18/64
x= -1/3
x = -0.3
Answer:
1 exponential decay and 78%
