20%=0.20
15.99 • 0.20 = 3.198
15.99 - 3.198 = 12.792
12.792 = $12.79

Hello,
which principle?
f(x)=-x²+2x
==>f'(x)= -2x+2
You mean maybe this
f(x+h)=-(x+h)²+2(x+h)= -(x²+2hx+h²)+2x+2h
f(x)=-x²+2x
19/50 when you divide both the numerator and the denominator by 2.
The other endpoint would have to be (-5,2), going off the definition of a midpoint. Since 3 is for units to the right of -1, that would mean that the other end point would have to be 4 units to the left, which is -5.
