Answer:
Your answer is C
Step-by-step explanation:
0.5 = Five tenths
and
0.05 = five hundredths
This is because 0.5 is like 50 cents and 0.05 is like 5 cents
The rest are wrong because A: 0.05 simply can't be bigger than 0.5
B is wrong because they aren't equal to each other
and D is wrong because 0.05 + 0.5 = 0.55
So,

1. Graph each inequality separately.
2. Choose a test point to determine which side of the line needs to be shaded.
3. The solution to the system will be the area where the shadings from each inequality overlap one another (purple area)
As for the system of inequalities we say it's unbounded.
Answer: y=5x-8
Step-by-step explanation: slope intercept form is y=mx+b. M stands for the slope and B stands for the y-intercept. You just need to input what the question is telling you.
