There is not enough Information.
A polygon must have at least 3 sides, but a curved angle isn't a side. This would result in you getting an oval. In short, it would not be a polygon. Hope this helps!
it is false because a sphere is basically a three- dimensional circle. It is a polyhedron.
6.5 = - 1/2(5) + 9
6.5 = - 2.5 + 9 which is the same as 6.5 = 9 - 2.5
6.5 = 6.5
So yes, this ordered pair IS a solution.
