A(b)=10*((b+7)/2)
A(b)=5(b+7)
b+7=A/5
b=A/5 - 7
B(a) = a/5 - 7

Step-by-step explanation:
Simple...
you have:
-2x+5y=10
re-write in y=mx+b form...
-2x+5y=10
+2x +2x
5y=2x+10
Now divide....
5y=2x+10

y=

Now it's easy to see the slope and y-intercept...
Slope:

Y-intercept:2
Thus, your answer.
5^5/5^8= 3125/390625 = 5/625 = 1/125
(1/5)^3 = 1/125
