How do you graph the inequality x > 3?

Back

To graph x > 3, draw a number line, place an open circle on 3 (indicating 3 is not included), and shade to the right to show all numbers greater than 3.

What does the inequality t ≥ -4 signify in a real-world context?

Back

It signifies that the temperature will be at least -4 degrees, meaning it can be -4 degrees or any temperature higher.

How would you express the statement 'the score must be less than 50' as an inequality?

Back

The inequality would be s < 50, where s represents the score.

Front

What does the inequality 1/2 > b mean?

Back

It means that the value of b must be less than 1/2.

How do you determine if a graph represents the inequality 5 ≥ x?

Back

The graph should show a closed circle at 5 and shade to the left, indicating that all values less than or equal to 5 are included.

Front

What is the significance of the inequality symbol '<'?

Back

The symbol '<' means 'less than', indicating that the value on the left is smaller than the value on the right.
