Step-by-step explanation:
it is right
The first one doesn’t represent a function. This is because it uses the same x-value twice.
Answer:
(0, -9).
Step-by-step explanation:
The general form of the equation of a circle is:
(x - a)^2 + (y - b)^2 = r^2
where the center = (a, b).
x2 + (y + 9)2 = 25
Comparing this to the general form we see that the center = (0, -9).
