Answer:
B.
Step-by-step explanation:
The graph that is going to show the function, has two parts: one for numbers equal or less than 3 and the other for numbers greater than 3
Then, for x≤3, the function is f(x) = 4. This is a constant so the graph is a horizontal line.
Additionally, for x>3, the function is f(x)=12x. This is a straight line with a positive slope. 
So, the answer that follows these 2 conditions is B.

Answer:
1. -19x
3. 23 -  8x
5. -18x + 2y
Step-by-step explanation:
first: 3x - x = 2x 
2x - 22x = -20x
-20x + x = -19x
second one: 
8 - (-15) = 23
12x - 20x = -8 x 
23 - 8x
third: 
-10x - 8x = -18x
3y - y = 2y
-18x + 2y
