A parabola has focus (5,7) and directrix y = 0 (the x -axis). Write an equation that says point (x, y) is on the parabola. You do not need to put it into vertex form. If it's helpful, draw a sketch of
the parabola.

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.

How do you use the elimination method for this question? explain, because i really want to understand!

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab
