Wed Jun 3 signments a Circles: Unit test Graph the circle x² + y2 + 16x - 16y + 124 = 0. y 8 6 4 2 2 2 4 6 8 -4 -6

the andwer please thank you

Answer 1

e 2 + y2 + 168 -16y +124 - 0 we have to convert it tot into standard form of equation (x-4) ² + (y-k) ² = 12 where Chik is the center and r is the radius we have to rewrite the by using completing square method be equation 1²- 16g) + 12470 as (x² + 16x) +

Add 64 with each bracket and equalize by putting is rett side. right (x ² + 16x+64) + Cy²- 160 +64) + 124 = 64164 (x+8)² + (y-8)² = 64 +64 - 124 (x+8) 2 + cy-8) ² Col + 8)² + cy-8)² = 2² Now this is in standard form where Chok) = (-88) and Vadius +

12 2) 8 10 radius (2) 6 -4 -2 -izo 7 2 46 8 x -8
