Answer:
The slope is -4 over -5
Step-by-step explanation:
Your equation should be y2-y1 over x2-x1. At first you will get -8 over -10 then you simplify and get -4 over -5
Area of a semicircle =

r² / 2
r= 5/2 = 2.5
So: A= 3.14 x 2.5² / 2 A = 9.8125 so rounding to the nearest hundredth is A=9.81
Answer:
x = -9/2
Step-by-step explanation:
16 + 4(x) = -2
4x = -2 - 16
4x = -18
x = -18/4
x = -9/2
