Answer:
D is correct.
Step-by-step explanation:
(x + 2)^2 + (y - 6)^2 = r^2

r^2= (10 - 6)^2
r^2=16
C. Heart

Answer:
The average is 124
Step-by-step explanation:
When x=2 substitute into the equation given above
-3^2+79
9+79=88...(1)
When x=4
-3^4+79
81+79=160(2)
Average of (1) and (2)
160+88/2
=248/2
=124
Therefore the average rate is 124
