To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
Is there any picture or something ?
<span>3x + 5y = 2 can be solved for 5y and then for y: 5y = -3x + 2, and so
y = (-3/5)x + 2/5. Slope is -3/5 and y-intercept is (0, 2/5). If you want more info, please ask specifically for what you want.

Answer:a=3/4
b=3/4
Step-by-step explanation:
3a+5b=6
9a+7b=12
-3(3a+5b)=-3(6)
9a+7b=12
-9a-15b=-18
9a+7b=12
-8b=-6
b=3/4
3a+5(3/4)=6
3a+15/4=6
3a=9/4
a=3/4
