f(x)=1-x^2. Looking for the vertex and an equation of the line of symmetry. f(x)=-x^2+5x+36 Looking for the x, and Y coordinates. I seem to be entering the answers backwards, cannot understand. Please help.

Stuck with one more.. f(x)= -x^2 + 2x + 8 I found the vertex, and the axis, but am having trouble putting my x intercepts in order. I know the Y intercept, what is wrong with me? :-) Homework, eh, I'd rather be hiking..

x^2 + 14x - 4 = 0 Solve please?

Dick mows the lawn in 7 hrs. Mary can do the same yard in 6 hrs. How much time would it take for them to mow the lawn together?
