There isn't a factor that isn't prime or composite.
Answer:
Step-by-step explanation:
The vertex is halfway between focus and directrix, at (0,0).
The equation has the form y = ax².
Focal length p = distance between focus and vertex = 1
p = 1/|4a|
1 = 1/|4a|
|a| = ¼
The focus lies below the vertex, so the parabola opens downwards and a<0.
y = -¼x²
Is the answer 25? Thats what I got.
Answer:
m + 8
Step-by-step explanation:
you start with the original number of marbles, m, and you ADD 8 more to the group.
Original number (m) + 8 more
M = 8
