Answer:
(-4,1)
Step-by-step explanation:
The given parabola is

When we rewrite in vertex form, we get;

Or

When we compare to:

We have 4p=-4
This means p=-1
But the vertex is at:
(-4,2)
Since it is a vertical parabola that opens down, the focus is one unit(|p|=1) below the vertex.
Hence the focus is (-4,1)
Answer:
Step-by-step explanation:
65m + 40 = 55m + 190
65m - 55m = 190 - 40
10m = 150
m = 15 months
