What is the value of x in the equation 8x-48 when y=4

Witch represents the inverse of the function f(x)=1/4x-12

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry. how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.

Use long division to indentify (12xto the second power+15x-8)divided by 3x
