Your answer should be 32. If it's 8(2)^2.
Step-by-step explanation:
1) supplementary
2) complementary
3) neither
4) neither
5) supplementary
6) complementary
7) supplementary
8) neither
9) complementary
This looks like a parabola so:
y=x^2 - 20x + 15 --> x^2 - 20x +15=y
(x^2 -20x)=y - 15 --> (x - 10)^2=y - 15 +100 ( used complete the square)
(x - 10)^2=y + 85
Two points give you a line. A third point (often called a check-point) is used to confirm the accuracy of your first two points. If all three line up, you have confirmed you have the correct line.
