W18 MATH TEKS 6.9B Representing 1-step/variable inequalities

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using inequality symbols such as <, >, ≤, or ≥.

Front

What do the symbols ≤ and ≥ represent?

Back

The symbol ≤ means 'less than or equal to', and the symbol ≥ means 'greater than or equal to'.

Front

How do you represent the inequality 'x is greater than 3' in symbols?

Back

x > 3

Front

What does the inequality x < 5 mean?

Back

It means that x can be any number less than 5.

Front

When graphing the inequality x ≥ 2, what type of circle is used at 2?

Back

A closed circle is used at 2 to indicate that 2 is included in the solution.

Front

What is the solution set for the inequality x < 4?

Back

The solution set includes all numbers less than 4.

Front

How do you write the inequality for the graph that shows all numbers greater than 5?

Back

x > 5

Front

What is the difference between an open circle and a closed circle on a number line?

Back

An open circle indicates that the number is not included in the solution, while a closed circle indicates that it is included.

Front

What does the inequality x ≤ 7 represent?

Back

It represents all numbers that are less than or equal to 7.

Front

If x > 2, what numbers are included in the solution?

Back

All numbers greater than 2, but not including 2 itself.
