Answer:
what?
Step-by-step explanation:
20 hours. You find this by dividing 150 by 10 and then multiplying that by 2.
To find the vertex use -b/2a (for the x value which is also the axis of symmetry)
So 2/-2 = -1 Therefore the axis of symmetry is x=-1 Plug in for the y value:
y= -(-1)^2 -2(-1) + 1 y=-1 + 2 + 1 y=2 Vertex (-1,2)
Answer:
2 Numbers; -10, and 10.
