Find the length of the missing side. The triangle is not drawn to scale.
20.
D. 100
A. 10
c. 28
B. 48

A: 10

Step-by-step explanation:

Using  Pythagorean theorem we know a^2+b^2=c^2

8^2+6^2=?^2

64+36=?^2

100=?^2

?=10

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
