Answer:
f(-4) = -12
Step-by-step explanation:

To calculate f(-4), we need to substitute x in our equation above with -4:

Note that 2*(-4) = -8
Answer: f(-4) = -12
To isolate x, we will first subtract 0.8 from both sides.
0.6x + 0.8 = 1.4
-0.8 -0.8
0.6x = 0.6
Now all we have to do is divide both sides by 0.6, because it is the number besides x.
0.6x/0.6 = 0.6/0.6
x = 1
So you get the answer of x = 1.
