What does the symbol '>' mean in inequalities?

Back

The symbol '>' means 'greater than'. For example, x > 5 means x is greater than 5.

Front

What does the symbol '<' mean in inequalities?

Back

The symbol '<' means 'less than'. For example, y < 3 means y is less than 3.

Front

What does the symbol '≥' mean in inequalities?

Back

The symbol '≥' means 'greater than or equal to'. For example, z ≥ 4 means z is greater than or equal to 4.

Front

What does the symbol '≤' mean in inequalities?

Back

The symbol '≤' means 'less than or equal to'. For example, a ≤ 10 means a is less than or equal to 10.

Front

How do you graph the inequality x < 2?

Back

To graph x < 2, draw a number line, place an open circle at 2, and shade to the left.

Front

How do you graph the inequality y ≥ -1?

Back

To graph y ≥ -1, draw a number line, place a closed circle at -1, and shade to the right.

Front

What does the inequality s ≤ 18 represent?

Back

The inequality s ≤ 18 means that the number of students s is less than or equal to 18.

Front

Which graph represents the inequality k < 3?

Back

The graph for k < 3 has an open circle at 3 and shades to the left.

Front

If p > 2, what does this mean?

Back

If p > 2, it means that p can be any number greater than 2.
