Unformatted text preview: 9 7 4 5 6 3 2 0 1 1 2 3 4 5 6 8 7 In interval notation, we write this is 10 9 (∞,2] ∨ (3,∞)
Graph the compound inequality 6 < x ≤ 5
In this case, after circling the endpoints, we note that all other values of x must satisfy BOTH conditions: they must be both GREATER THAN 6 and LESS THAN 5.
Now, where on the number line, are all of these numbers? Between 6 and 5. 10 9 8 7 5 6 4 3 2 0 1 1 2 3 4 5 6 7 8 To show this, we simply CONNECT THE DOTS. There are NO ARROWS. 10 9 In interval notation, we write this is (6,5] Solving Linear Inequalities
Solve the following inequality and graph the solution set on the number line.
2x 7 ≥ 9
Solve exactly the same as you would if it were an equation. 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 1...
