We want to factor:
This may seem tricky because of the high powers, but remember that
. Then we can factor it as:
Answer:
8x-40
Step-by-step explanation:
The inverse of this function is f^-1(x)=x/9
1) given
2) definition of linear pair
3) definition of linear pair and supplementary
4) definition of supplementary supplementary angles add to 180
5) the measure of angle one plus the measure of angle 2 plus the measure of angle 3 equals 180
6) substitution in lines 4 and 5
7) the measure of angle one plus the measure of angle 2 equals measure of angle 4 by algebra and simplification
Answer:60
Step-by-step explanation:
0
