F(x) = -2 + 8
f(x) = 6
No matter what x is, it does not change the value of f(x).
f(-1,8) = 6
Answer: 6
Answer:
a. 
b. 
c. 
Step-by-step explanation:
a. 
b. 
c. 
First we expand the brackets:
-2a + 8 + 6a = 36
4a + 8 = 36
We then need to get the a's onto one side and the numbers onto the other:
4a = 28
We can then divide to get an x by itself:
a = 28/4 = 7
