F(8)=4(8)-2+7(8)
f(8)=32-2+56
f(8)=86
f(-5)=4(-5)-2+7(-5)
f(-5)=-20-2+2
f(-5)=20
f(0)=4(0)-2+7(0)
f(0)=0-2+0
f(0)=-2

C I’m pretty sure that’s what is it
First find x: y= -2x+4 so you take that and substitute it into your second equation -x+3(-2x+4)=-9 ---> -7x+12=-9 ---> -7x= 3 ---> x=-3/7
Now you can find y by substituting x: y=-2x+4 ---> y=-2(-3/7) +4 ---> y=
Answer:
=-26
Step-by-step explanation:
f(n) = 7n – 5
Let n = -3
f(-3) = 7*(-3) – 5
Multiply first
= -21-5
=-26
