Find the vertex of the graph of the equation....

1. \(x - y^2 + 8y = 13\)

2. \(y = -2x^2 + 8x - 15\)

Arrange first one as    x = y^2 -8y+13           then the 'y' value of the vertex will be found   (this is a sideways parabola)

as   - b/2a     where b = - 8  a =1     use THIS value in the equation to find the 'x' value

y = -2x^2 + 8x -15        vertex 'x' value will  be   -b/2a   b = 8     a = -2      use THIS value in the equation to find the vertex 'y' value

I really need the answer!  Can't you just give me the answer?

It's not my homework. It's a bet, with a friend who is smart, (unlike me).

Could you please give me a full solution?

For a full solution, EP will need to chase a half-pint of Magnesia Milk with Ipecac, because he will have to shit while puking up the answer.
