Worked Solution & Example Answer:The table below gives two inequalities in T (a temperature in °C), and a description of two inequalities in T - Junior Cycle Mathematics - Question d/e - 2022
Step 1
Step 2
Graph the inequality T < 36
Answer
To graph the inequality T < 36 on the number line:
- Draw a number line with tick marks at 34, 35, 36, 37, 38, 39, and 40.
- Use an open circle at 36 to indicate that 36 is not included in the solution set.
- Shade to the left of 36 to show all values less than 36.
The graph would appear as follows:
34 35 O---|---|---|---|---|---
36 37 38 39 40
The shaded area extends from 34 to just before 36.
