Question

What Ian the center of a circle represented by the equation (x+9)squared + (y-6)squared = 10squared

Answer 1

(- 9, 6 )

Explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h. k) are the coordinates of the centre and r the radius

(x + 9)² + (y - 6)² = 10², that is

(x - (- 9))² + (y - 6)² = 10² ← is in standard form

with centre = (- 9, 6 ) and r = 10
