Answer:
18
Step-by-step explanation:
9 x 2 = 18
radius x 2 = diameter
the answer is 22 hope this helps
7(-7)= -49
-49+149=100
100-56=44
44/2=22
x=3
try different values on the line! plug them in and you'll see that every x value is 3!
use -4y for x in the second equation
-4 y + 5 y = 2
so
y = 2
then x = -4(2) = -8
(-8 , 2)
