Answer:
hey, are these two questions or one simultaneous question?
Answer:
the coordinate of the focus is: (0, 1/2)
the equation of the directrix is: y=-1/2
Step-by-step explanation: The standard equation for a parabola that opens upward- parallel to the y-axis, is: x2=4ay. Meaning, a = distance from the vertex to focus and the vertex is at origin: (0,0).
4a is equal to 2
a is equal to 2/4
a is equal to 1/2 or 0.5
9x^2 - 14x + 20x^2
= 9x^2 +20x^2 -14x
= 29x^2 -14x
