Answer:
w>-1
Step-by-step explanation:
1 Move terms 
53w-56w<16-13
2 Collect like terms then subtract
-3w< 3
3 Divide both sides by -3
Answer: w>-1

Answer:
1. No vertical compression or stretching but will open up downward.
2. 1/4 vertical stretch
3. 4 vertical compression
Step-by-step explanation:
Any time your dealing with vertical stretching or compression it will always be the number before the parentheses. 
So in 1. it is - or basically -1 which means the parabola will be open up downward. And in this problem there is no stretching or compression
2. Is the 1/4 is a vertical stretch 
3. 4 is a vertical compression. 
Or what also could help is when the number before the parentheses is bigger such as number 4 the closer together the parabola will be. And the smaller the number like 1/4 the wider the parabola will be.
