You can solve it with the numbers you already have.
so, 23 - 15 = 8
so 15 + 8 = 23
b is 8 (:

Answer:
It should be the top left graph where there is point (1,1) and (-1, -1) y = 1/x
Step-by-step explanation:
from the original graph, I see:
f(x) = 2/x because f(2) = 1 = 2/2
f(1/4)= 2/(1/4) = 2
...
so then f(2x) compresses f(x) horizontally by a factor of 2
so f(2x) = 2/(2x) = 1/x
Line D and C because they are not parallel but distorted or unsymmetrical
25/100=30/x x=120 (30+70y)/(120+100y)=50/100 100y=?
