Question 428022: 1) Check whether 9 is a solution to the inequality 20 - x > = x + 2. Show all work. Note: The > = means greater than or equal to.
2) Explain what the graph of r > -5.5 would look like on a number line

You can put this solution on YOUR website!
1) Check whether 9 is a solution to the inequality 20 - x > = x + 2. Show all work. Note: The > = means greater than or equal to.
First, solve the inequality
20 - x >= x + 2
2x <= 18
x <= 9
You can see 9 is one of the solutions of the inequality.
2) Explain what the graph of r > -5.5 would look like on a number line.
On the number line, you put -5.5 (on the left side of 0).
Since r > -5.5, you highlight the left side of -5.5 and use ")" sign which mean the solution set does not include -5.5.
