x=-9
Step-by-step explanation:

As the bases(3) are same,
we can conclude that the powers are equal.
Hence,

If c is cents (¢) then she would receive $19.74 or in cents that would be 1974¢
1 I think is the answer I hop it helped.
We have the following equation:
x2 + y2 + 6y - 72 = 0
Rewriting we have:
x2 + y2 + 6y = 72
Complete squares we have:
x2 + y2 + 6y + (6/2) ^ 2 = 72 + (6/2) ^ 2
x2 + y2 + 6y + (3) ^ 2 = 72 + (3) ^ 2
x2 + y2 + 6y + 9 = 72 + 9
x2 + (y + 3) 2 = 81
So, the center is:
(0, -3)
The radio is:
r = 9
Answer:
(0, -3)
r = 9
90 counterclockwise hope I’m right
