Answer:
x = -7
Step-by-step explanation:
The vertex form of this equation tells us it is a downward-opening parabola with its vertex at (-7, -3). The line of symmetry is the vertical line through the vertex: x = -7.
___
Vertex form is ...
y = a(x -h) +k
where a is the vertical expansion factor, and (h, k) is the vertex. When a < 0, the parabola opens downward. When a > 0, it opens upward. (When a=0, the "parabola" is a horizontal line at y=k.)
Answer: $2.60

Answer:
Just add 5 to every number.
Step-by-step explanation:
Your answer would be 24 marbles. This is because if you add up all the number of pulls, you get 20, which means we would need to multiply all of the results by 3 to see how many pulls you would get in a bag of 60, and so 8 x 3 = 24. I hope this helps,
