Answer:
y/x = (a + b) / (m + n)
Step-by-step explanation:
-(xb − ym) = -yn + xa
Distribute:
-xb + ym = -yn + xa
Combine like terms:
ym + yn = xa + xb
Factor:
y (m + n) = x (a + b)
Rearrange:
y/x = (a + b) / (m + n)
<span> f(x) = –81 (4/3) X-1 f(x) = –81 (-3/4) </span>
The answer has to be letter A .
