9-x^2+y^2>0

9 - x^{2} + y^{2} > 0

(h, k) = (0, 0), a = 3, b = 3

Solution steps

9 - x^{2} + y^{2} > 0

Rewrite

9 - x^{2} + y^{2} > 0

in the form of a standard hyperbola equation

\frac{( x - 0 ) ^{2}}{3 ^{2}} - \frac{( y - 0 ) ^{2}}{3 ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (0, 0), a = 3, b = 3

- 2 x^{2} + 8 y^{2} - 8 x - 16 y = 30

4 y^{2} - 9 x^{2} + 16 y + 18 x - 29 = 0

4 x^{2} - y^{2} - 24 x - 8 y = 44

4 x^{2} - 9 y^{2} + 16 x + 18 y - 11 = 0

(16) x^{2} + (256) x - (361) y^{2} - 3610 y + (4273) = 0
