The solution set of the example inequality, 2•x + 3 ≤ -3, is the option;
- (-∞, -3]
How can the solution set of an inequality be found?
A possible inequality that can be used to get one of the options, (the inequality is not included in the question) is as follows;
- 2•x + 3 ≤ -3
Solving the above inequality, we have;
2•x + 3 ≤ -3
2•x ≤ -3 - 3 = -6
2•x ≤ -6
Therefore;
x ≤ -6 ÷ 2 = -3
x ≤ -3
Which gives;
- -∞ < x ≤ -3
-∞ < x ≤ -3 in interval notation is (-∞, -3]
The solution set of the inequality, 2•x + 3 ≤ -3, is therefore the option;
- (-∞, -3]
