You can do this by completing the square
x^2 - 14x + y^2 + 8 = 16
(x - 7)^2 - 49 + (y + 4)^2 - 16 = 16
(x - 7)^2 + (y + 4)^2 = 16 + 16 + 49 = 81
so the center is at (7 , -4) and radius = sqrt81 = 9
If 10 is decreased to 6 it would be 60% a
Answer:10
Step-by-step explanation:
2x+3y=160
-2x+7y=25 I hope that helps!!
