Exercise 39 Page 59

Which side of the number line should be shaded according to the inequality?

Inequality: z≥1.3
Graph:

Practice makes perfect
Let's begin by interpreting the given set-builder notation. {z | 1.3 ≤ z} 1.3 is less than or equal to z

This solution set can be written as an inequality. z ≥ 1.3 To graph this inequality, we place a closed circle at 1.3 on a number line. Since z is greater than 1.3, the solution set includes all numbers that are above 1.3. Therefore, we should shade everything to the right of the closed circle.
