2x + 6 = 2
- 6. - 6
-------------------------
2x = -4
---- -----
2. 2
x = -2
2. 2(6 -2y) = -1(4y-9)
12 -4y = -4y + 9
+4y. +4y
----------------------------
.12 /=\ 9
No solution
3. 2z-6 = 2(z+2) + 10
2z -6 = 2z + 4 + 10
2z -6 = 2z +14
-2z. -2z
-6 /=\ 14
No solution.
Answer:
D) -122
Step-by-step explanation:
Given:

We need to find f(-4).
Now by substituting the value of x =-4 in above equation we get;

By using PEDMAS we will solve for exponential function first we get;
Now we know that 
So we get;

Now using PEDMAS we will solve division.

Now using PEDMAS we solve multiplication.

Finally by subtraction we get;
