The answer is -2/3x + 6 because it is the only answer with a negative fraction.
The center-radius form of the circle equation is in the format
(x – h)²+ (y – k)² = r²
with the center being at the point (h, k) and the radius being "r"
So, just plug in the (-5,3) and you get:
(x+5)²+(y-3)²=16
Answer:
X=12
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.

Answer: 24pi feet</h3>
Work Shown:
The area is 144pi square feet. So A = 144pi is plugged into the formula below to isolate r
A = pi*r^2
144pi = pi*r^2
144 = r^2 .... divide both sides by pi, the pi terms cancel
r^2 = 144
r = sqrt(144) ... take the square root of both sides
r = 12
This is plugged into the circumference of a circle formula
C = 2*pi*r
C = 2*pi*12
C = 2*12*pi
C = 24pi
This is approximately equal to 75.36 when you use the approximation pi = 3.14
The 3rd one, dear. hope this helped.
