Answer 1

thank you for your help

Answer 2

what is the center of this circle? 7x squared plus 7y squared minus 98x minus 112y plus 679=0

Answer 3

7x²+7y²-98x-112y+679=0
7(x²+y²-14x-16y)+679=0
7(x-7)²+7(y-8)²=112

So the center is (7,8)

Answer 4

what is the radius of this equation: 3x squared plus 3y squared plus 12x minus 24y minus 48=0
