Answer:
Step-by-step explanation:
Let the number = x
3x + 9 = 2x - 6 Looks like you are going to get something negative here.
Subtract 2x from both sides.
3x - 2x + 9 = 2x - 2x - 6
x + 9 = -6
Subtract 9 from both sides.
x + 9 - 9 = - 6 - 9
Combine
x = - 15
From the graph we can see that the horiz. directrix is 1 unit down from the vertex, which in turn is (1,4). The focus is located the same distance (1) upward from the vertex, that is, at (1, 5).
