The center of a circle of the form:
is (a, b) and its radius is r.
Comparing the given equation of circle we can write:
a = 20
b = 0.05
r² = 81
This means the center of the circle is (20, 0.05) and the radius of the circle is 9.
OK.
You said that -8 = 7a - 11
Add 11 to each side: 3 = 7a
Divide each side by 7 : 3/7 = a
