Hey there. To find the answer solve 8^3=512.
Count the rows and columns of each to get C as your answer.
This ODE is separable; we have

Integrating both sides gives a general solution of

B is the only choice that is applicable.
Complementary angles add up to 90°
and supplementary angles add up to 180°
Add the two angles together
82+98=180
So the measure of these two angles are supplementary
Go up six on the y intercept. Then from 6 go up 1 and over 4.
