Answer:
A. -6
Step-by-step explanation:
[tex]f(x)=3x-1\\\\[/tex]
In order to find [tex]f(-2)[/tex] we will plugin [tex]x=-2[/tex]
[tex]f(-2) = 3(-2)-1\\f(-2)=(3\times(-2))-1\\f(-2)=-6-1[/tex]
[tex]f(-2)=-7[/tex]
[tex]g(x)=-x+6[/tex]
In order to find [tex]g(5)[/tex] we will plugin [tex]x=5[/tex]
[tex]g(5)=-5+6[/tex]
[tex]g(5)=1[/tex]
[tex]f(-2)+g(5)\\=-7+1\\=-6[/tex]
∴ [tex]f(-2)+g(5)=-6[/tex]
