Question

Which equations represent hyperbolas?

49x² -98x-64y² + 256y-2,831-0
6x²-12x+54y +108y-426-0
4x²+32x-25-250y+ 589 = 0
100x-648x+100y+200y-6,704-0
196x+36y²+216y-1,244-0
81x²+512x-64y - 324y-3,836-0

Answer 1

81x2 + 512х - 647y^2

- 324y - 3,836=0

Explanation:

This equation matches the standard hyperbola form. The x and y terms have opposite signs, which signifies a hyperbola in this case.
