Identify the center and radius of the circle (x – 5) + (y + 1)2 = 4.

x= 7 - 2y, y∈ ℝ

Step-by-step explanation:

Remove unnecessary parentheses

x-5 + (y+1) 2+4

Distribute 2 through the parentheses

x-5 + 2y+2+4

Calculate the sum

x-3 + 2y=4

Move the expression to the right-hand side and change its sing

x=4+3-2y

Add the numbers

x=7-2y

Write the solution x in parametric form

x=7-27,y∈ ℝ
