Question 168945: Will someone PLEASE HELP!!!!
1. Write an equation for the ellipse iwth end points of the major axis at (7,1) & (-7,1) and end points of the minor axis at (0,5) & (0,-3)
2. Write 36x^2-360x-25y^2-100y=100 in standard form. Then state whether the graphs of the equation is a parabola, circle, ellipse, or hyperbola.
Thank you

1. %28x-0%29%5E2%2F7%5E2+%2B+%28y-1%29%5E2%2F4%5E2+=+1


2. factoring __ 36(x^2-10x)-25(y^2+4y)=100

completing the squares __ 36(x^2-10x+25)-25(y^2+4y+4)=100+(36*25)-(25*4)

36(x-5)^2 - 25(y+2)^2 = 900

dividing by 900 __ %28x-5%29%5E2%2F5%5E2+-+%28y%2B2%29%5E2%2F6%5E2+=+1 __ this is a hyperbola
