A circle is represented by the equation x^2 + 8x + y^2 - 12y = -29. Describe the algebraic techniques needed to rewrite the equation in standard form. Identify the center and radius of the circle. Show your work.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

you could deduce the conclusion directly using the facts pertaining to the specific situation.
