Find the vertices and foci of the hyperbola with equation quantity x plus 5 squared divided by 81 minus the quantity of y minus 3 squared divided by 144 = 1.
Vertices: (4, 3), (14, 3); Foci: (20, 3), (10, 3)
Vertices: (3, 7), (3, 17); Foci: (3, 17), (3, 7)
Vertices: (7, 3), (17, 3); Foci: (17, 3), (7, 3)
Vertices: (3, 4), (3, 14); Foci: (3, 20), (3, 10)

Best ResponseYou've already chosen the best response.0The "center" of our hyperbola has been shifted to (5,3). To find our vertex on the right branch, let's `add a` to the xcoordinate. We just want to move a distance of `a to the right` to get to the vertex. Do you understand what your `a` and `b` values are?
