Question

What is the result of isolating y2 in the equation below?

(x+4)² + y² = 22
OA. 2=-²2-8x+6
OB. 2=x2-8x+6
OC. 2²=22-x²
OD. 2²=-x²-8x + 16

Answer 1

To isolate y² in the equation (x+4)² + y² = 22, you need to move the (x+4)² term to the other side of the equation by subtracting it from both sides. The result is y² = 22 - (x+4)².

Step-by-step explanation:

To isolate y² in the equation (x+4)² + y² = 22, we need to move the (x+4)² term to the other side of the equation.

This can be done by subtracting (x+4)² from both sides:

y² = 22 - (x+4)²

Therefore, the result of isolating y² in the equation is y² = 22 - (x+4)², which corresponds to option OC. 2²=22-x².
