Write your solution as an inequality. For example, x>-4 or x (less than or equal to sign) 5 to represent the solution use a ________ on a number line if the variable can be equal to the boundary number (greater than equal or less then equal)

Question

Us an ___________ on a number line if the variable can. Of equal the boundary number (< or >)

Answer 1

To represent the solution of an inequality:

1. Use a closed circle on a number line if the variable can be equal to the boundary number (for example, when the inequality is greater than or equal to \( \geq \) or less than or equal to \( \leq \)).

2. Use an open circle on a number line if the variable cannot equal the boundary number (for example, when the inequality is strictly greater than \( > \) or strictly less than \( < \)).

This way, you can visually communicate whether the boundary is included in the solution set or not.
