Question

The archway of the main entrance of a university is modeled by the quadratic equation y = -x2 + 6x. The university is hanging a banner at the main entrance at an angle defined by the equation 4y = 21 − x. At what points should the banner be attached to the archway?
A. (1, 5.5) and (5.25, 6.56)
B. (1, 5) and (5.25, 3.94)
C. (1.5, 4.87) and (3.5, 4.37)
D. (1.5, 5.62) and (3.5, 6.12)
E. There is no real solution.

Hey people I need help pronto

Answer 2

It's basically asking where the two equations intersect, so solve for a variable in one and substitute it into the other.
Based on the answers you're given, I think this might be a calculator problem, in which case you can make a TI83 o4 84 calculator solve for the intersections.
Otherwise, you will just end up using the quadratic formula but at some point will have to use a calculator to get the radicals in decimal form
