Distribute the negative sign
![7x^2-3x-6](https://tex.z-dn.net/?f=7x%5E2-3x-6)
Combine like terms
-9x^2 + 7x^2 = -2x^2
9x - 3x = 6x
13 - 6 = 7
![-2x^2 +6x + 7](https://tex.z-dn.net/?f=-2x%5E2%20%2B6x%20%2B%207)

Answer: 10.2
Step-by-step explanation: 64 x 0.16 = 10.24
First, solve the inequality:
![7(4x - 1 ) + 6x \ \textgreater \ -279\\ 28x-7+6x\ \textgreater \ -279\\ 34x\ \textgreater \ -272\\ x\ \textgreater \ -8](https://tex.z-dn.net/?f=7%284x%20-%201%20%29%20%2B%206x%20%5C%20%5Ctextgreater%20%5C%20%20-279%5C%5C%0A28x-7%2B6x%5C%20%5Ctextgreater%20%5C%20-279%5C%5C%0A34x%5C%20%5Ctextgreater%20%5C%20-272%5C%5C%0Ax%5C%20%5Ctextgreater%20%5C%20-8)
Since x is <u>greater than</u> -8, you have the arrow point up the graph towards the positive side starting at -8.
Since it's greater than but not equal to -8, the circle is open.
Thus your graph is
D.
