Answer:
(x+4)² + (y+9)² = 100
Step-by-step explanation:
We want to find the equation of a circle with a radius of length 10 and a center at (-4, -9).
general equation of circle : (x-h)² + (y-k)² = r²
where (h,k) is at center and r = radius
the center is at (-4,-9) so h = -4 and k = -9 and the circle has a radius of 10 so r = 10
so we have (x-h)² + (y-k)² = r²
h = -4 , k = -9 and r = 10
(x-(-4))² + (y-(-9))² = 10²
==> apply double negative sign rule and remove parenthesis for -(-4) and -(-9)
(x+4)² + (y+9)² = 10²
==> simplify exponent
(x+4)² + (y+9)² = 100
and we are done!

Im not sure ut it looks like 3x over 3x would cancel eachother out.
Answer:
Reflect over x=-2 and dilate G'H'I' by a scale factor of 2 from point G
Step-by-step explanation:
First you'd have to reflect from x=-2 because its still on that line but the opposite way.
So we can already narrow it down to the second or last answer.
It wouldn't translate because that doesn't change the size. Its a dilation because the size has changed. Its dilated from point G because as you can see, G is the same point on both.
So the last answer choice is correct.
