1. Problem Description

The problem asks us to write the inequality in terms of xx that each of the given diagrams represents. The first diagram (a) is a number line, and the second diagram (b) is a shaded region in the xy-plane.

2. Solution Steps

(a) The number line has a solid circle at 3-3 and an arrow pointing to the right. A solid circle means that 3-3 is included in the solution. The arrow pointing to the right means that all numbers greater than 3-3 are included. Thus, the inequality is x3x \ge -3.
(b) The shaded region is to the left of the vertical line x=1x=1. Since the line is dashed, the line x=1x=1 is not included in the solution. The inequality is thus x<1x < 1.

3. Final Answer

(a) x3x \ge -3
(b) x<1x < 1
