Solving and graphing one step inequalities-addition/subtraction

Front

What is an inequality?

Back

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

Front

What does the symbol '<' mean?

Back

The symbol '<' means 'less than'. For example, x < 5 means x is less than 5.

Front

What does the symbol '>' mean?

Back

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

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'. For example, x ≤ 5 means x is less than or equal to 5.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'. For example, x ≥ 5 means x is greater than or equal to 5.

How do you solve the inequality -4 + y < -8?

Back

Add 4 to both sides: y < -4.

Front

What is the solution to the inequality x ≥ 3?

Back

The solution includes all numbers greater than or equal to 3.

Front

How do you represent 'No More Than' in an inequality?

Back

'No More Than' is represented by the symbol '≤'.

Front

What is the solution to the inequality x > 5?

Back

The solution includes all numbers greater than 5.

Front

How do you graph the inequality x < 5?

Back

Shade the area to the left of 5 on a number line, and use an open circle at 5.
