Referenced from lesson Simple Inequalities (Spring, 2021)
Each inequality expression in the first column contains a number.
Decide whether or not that number is a solution to the expression and place it in the appropriate column.
Then identify 4 solution and 4 non-solution values for x.
-
Solutions will make the expression
true. -
Non-Solutions will make the expression
false.
Challenge yourself to use negatives, positives, fractions, decimals, etc. for your x values.
| Expression | 4 solutions that evaluate to true |
4 non-solutions that evaluate to false |
|---|---|---|
(> x 2) |
||
(<= x -2) |
||
(< x 3.5) |
||
(>= x -1) |
||
(> x -4) |
||
(<> x 2) |
1 For which inequalities was the number from the expression part of the solution?
2 For which inequalities was the number from the expression not part of the solution?
3 For which inequalities were the solutions on the left end of the number line?
4 For which inequalities were the solutions on the right end of the number line?
