34 Squared, I think if im wrong im very sorry
Answer:
a
Step-by-step explanation:
x+2y=-10
-x -x
2y=-10-x
y=(1/2)x-5
This is one of the lines and reduces the options to a or c.
3x-y=12
-3x -3x
-y=12-3x
y=3x-12
This is the line with the positive slope and since both lines match, the answer is a.
I think the answer is D hope that helps
Average= 9.625
average is when you add up all the numbers and divide by how many there are..
x,21,27,21,16,-2,-9,9
(x+21+27+21+16+-2+-9+9)/8=9.625
×8 both sides
x+21+27+21+16+-2+-9+9=77
x+83=77
-83 both sides
x= -6 degrees
