Step-by-step explanation:
Answer:
like for division?????????
Y² + 10z - 10y - yz = (y - 10)(y - z)
Directrix is x =1, so it is horizontal parabola.Vertex is between the focus and directrix on equal distance 5-x=x-1, 2x=6,
x=3. y -coordinate of the vertex for this parabola equals y-coordinate of the focus.
Vertex (3,2).
Focus has x=5 >1, so it is directed to the right.
