Question

What is the result of isolating x2 in the equation below?x2 + (y- 5)2 = 30O A. x = y2 + 10y+ 5B. x2 = 30 - 12c. x2 = -y2 + 10y+ 5D. x2 = -12 + 10y+ 25

Answer 1

$\begin{gathered} x^2+(y-5)^2=30\rightarrow \\ x^2=30-(y-5)^2\rightarrow \\ x^2=30-y^2+10y-25\rightarrow \\ x^2=-y^2+10y+5 \end{gathered}$
