Answer:

10c - 4d

Step-by-step explanation:

1. Rearrange the problem so similar variables are closer together

3c + 7c + 5d - 9d

2. Simplify the problem by adding like terms

3c + 7c = 10c

5d - 9d = -4d

3. Rewrite the problem so the variables are in ABC order

10c - 4d

Hope this helps :)

What are the coordinates of the vertex of the parabola y=x^2+2x-1

kozerog [31]

Y = x^2 + 2x - 1 = x^2 + 2x + 1 - 1 - 1 = (x + 1)^2 - 2
The vertex of a parabola given by y = a(x - h)^2 + k is (h, k).

Therefore, the vertex of y = (x + 1)^2 - 2 is (-1, -2)
