Take one step at a time. First, let's evaluate g(1):

g(1) = 2*1-3 = -1

now plug this into f: 

f(-1) = 5*-1 = -5. So the second answer is the right one.
-----------------------
Same approach for q 12, only now we have no value to fill in for x. What's confusing here is that the x's of f and g should not be mixed up. For the sake of clarity let's rewrite f as

f(z) = 5z + 9.

Now we'll write 3-4x everywhere we find a z. Ah, only one place.

f(g(x)) = 5(3-4x) + 9 = 15 - 20x + 9 = 24 - 20x

Which equations show you how to find 16-9?
Pie
The correct answer is B.
16-9=7
So, 7+9=16.

If we add to 9 only 1 (out of those 7) we have then 10, remaining 6.
9+1=10

Now, if to 10 we add the remaining 6 we will have the final 16.
10+6=16

16-9=7 <=> 9+7=16 <=> (9+1)+6=16

The answer would be B, (6,-3) because when you plug in the x and y values into the inequality, it is the only result that is true
