Answer 1

To convert an inequality into interval notation, solve the inequality for the variable and write the solution as an interval.

Step-by-step explanation:

To convert an inequality into interval notation, you need to determine the range of values that satisfy the inequality. Here are the steps:

1. First, solve the inequality for the variable.
2. If the inequality includes the less than or equal to (≤) or greater than or equal to (≥) symbols, use brackets [] for inclusive values. If the inequality includes only the less than (<) or greater than (>) symbols, use parentheses () for exclusive values.
3. Write the solution as an interval using the variable and the symbol used in the inequality.

For example, if you have the inequality x > 2, the solution in interval notation would be (2, ∞), which means all values greater than 2.
