Which of the following is a solution to the inequality below?
-6 > -12 - 8x
1) x=5
2) x= -3
3) x= -1
4) x= -10

The correct answer is -3/4. However that isn’t an answer choice, therefore I have no idea what to tell you

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
