13 of 25 would mean that the percent of error is 86%
After you combine like terms you will get 5p - 9m.
-3p + 8p is the same thing as 8p - 3, so you get 5p.
-2m + (-7m) is -9m
-3p and 8p are like terms.
-2m and -7m are also like terms.
F(x) = 1.25(38 - x)
Finding the inverse of a function:
y = f(x)
y = 1.25(38 - x)
Solve for x:
y = 1.25(38 - x)
y/1.25 = 38-x
x = 38 - y/1.25
Switch x and y.
y = 38 - x/1.25
f^-1(x) = 38 - x/1.25
G(4)=(4)2+3
g(4)=8+3
g(4)=11
The answer would be no solution. It comes out to 56=-49
