A common denominator is 12
Subtract the powers
c. 9-7 so 10^2
d. 8-1 so 5^7
2 or 3 I would say... hope that helps : )
A hyperbola with a center at (0, 0) can be defined as x²/a² − y²/b² = ±1.<span>
</span>The statement "<span>The symmetry of a hyperbola with a center at (h, k) only occurs at y = k" </span>is false, because a hyperbola have many different orientations.
It doesn't have to be symmetric about the lines y = k or x = h.
