1. Problem Description
The problem asks us to write the inequality in terms of 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 and an arrow pointing to the right. A solid circle means that is included in the solution. The arrow pointing to the right means that all numbers greater than are included. Thus, the inequality is .
(b) The shaded region is to the left of the vertical line . Since the line is dashed, the line is not included in the solution. The inequality is thus .
3. Final Answer
(a)
(b)
