The equation of the circle is (x - 1)^2 +(y + 9)^2 = 144
<h3>How to determine the circle equation?</h3>
The given parameters are:
Center, (a,b) = (1, -9)
Radius, r = 12
The circle equation is calculated as:
(x - a)^2 + (y- b)^2 = r^2
This gives
(x - 1)^2 +(y + 9)^2 = 12^2
Evaluate the exponent
(x - 1)^2 +(y + 9)^2 = 144
Hence, the equation of the circle is (x - 1)^2 +(y + 9)^2 = 144

Answer:
Step-by-step explanation:
The third line of the solution is incorrect. It should be ...
5x +2 = -5x +2
Then the one solution can be found:
10x = 0 . . . . . . . . . add 5x-2 to both sides
x = 0
