If the vertex of a parabola is (2,-9) and another point on the curve is (5,-18). what is the coefficient of the squared expression in the parabola's equation?

Point a is located at (0, 4), and point c is located at (−3, 5). find the x value for the point b that is located one fourth the distance from point a to point c. −0.25 −0.5 −0.75 −1

What is the value of x? enter your answer in the box. x = two intersecting tangents that form an angle of x degrees and an angle of 134 degrees.
