9((x-3)/9)^2+9((y+12)/9)^2=172

9 (\frac{x - 3}{9})^{2} + 9 (\frac{y + 12}{9})^{2} = 172

(a, b) = (3, - 12), r = 643

Solution steps

9 (\frac{x - 3}{9})^{2} + 9 (\frac{y + 12}{9})^{2} = 172

Rewrite

9 (\frac{x - 3}{9})^{2} + 9 (\frac{y + 12}{9})^{2} = 172

in the form of the standard circle equation

(x - 3)^{2} + (y - (- 12))^{2} = (643)^{2}

Therefore the circle properties are:

(a, b) = (3, - 12), r = 643

(x - 1.5)^{2} + (y + 2.5)^{2} = 1.15

(x + 2)^{2} + (y - 8)^{2} = 4^{2}

(x - 40)^{2} + (y - 0)^{2} = 0.1

3 x^{2} - 2 x + 3 + 3 y^{2} + 8 y + 48 = \frac{172}{3}

(x - 1)^{2} + (y + 5)^{2} < 4
