Answer:
D. 13 1/2
Step-by-step explanation:
2/3 x -2 = 7
2/3 x -2 + 2 = 7 + 2
2/3 x = 9
x = 9 (3/2)
x = 27/2
x = 13 1/2
the domain of the relation is C
a^2+b^2=a(2)^1.5
im not sure, just seems right
not sure which is the origional-
if the big one is the origiinal, then 1/2
if the small one is the origional- then 2-1
