Answer:

$\boxed{ \bold{ \huge{ { \sf{ - 13 {x}^{2} - 10x + 14}}}}}$

Step-by-step explanation:

$\sf{ - 9x - x - 7 {x}^{2} - 6 {x}^{2} + 8 + 6}$

Collect like terms

⇒ $\sf{ - 7 {x}^{2} - 6 {x}^{2} - 9x - x + 8 + 6}$

⇒ $\sf{ - 13 {x}^{2} - 10x + 8 + 6}$

Add the numbers

⇒ $\sf{ - 13 {x}^{2} - 10x + 14}$

Hope I helped!

Best regards!!

Given f(x) = 3x - 1 and g(x)= -x + 6, find f(-2) + g(5).<br> A. -6<br> B. 6<br> C. 8

marta [7]

Answer:

A. -6

Step-by-step explanation:

$f(x)=3x-1\\\\$

In order to find $f(-2)$ we will plugin $x=-2$

$f(-2) = 3(-2)-1\\f(-2)=(3\times(-2))-1\\f(-2)=-6-1$

$f(-2)=-7$

$g(x)=-x+6$

In order to find $g(5)$ we will plugin $x=5$

$g(5)=-5+6$

$g(5)=1$

$f(-2)+g(5)\\=-7+1\\=-6$

∴ $f(-2)+g(5)=-6$
