Answer:
B
Step-by-step explanation:
The equation of a circle is
(x-h)^2 + (y-k)^2 = r^2
h= 9, k = -7
r = 2, so r^2 = 4.
We now know that the equation must equal 4, so we can rule out answers A and C.
Plug in the values for h and k to get
(x-9)^2 + (y+7)^2 = 4
Choice B is correct!
Answer:
Yes
Step-by-step explanation:
Well let's solve it!
In order to solve this, plug in x into the equation.
Let's do the side on the LEFT of the equal sign first.
3(3+1) = 3(4) = 12
Now Let's do the side on the RIGHT of the equal sign.
3(3) + 3 = 9+3 = 12
So this means they are equal or congruent!

To find the percent, divide 9 by 27 to get a decimal, then multiply the decimal by 100 to get the percent:
9 / 27 = 0.333
0.333 x 100 = 33.3%
