One and Two step inequalities FLASHCARD

Front

What is an inequality?

Back

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

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'.

Front

How do you solve the inequality -3x ≤ 18?

Back

Divide both sides by -3, remembering to flip the inequality sign: x ≥ -6.

Front

When graphing the inequality b < 6, what type of circle is used?

Back

An open circle is used when graphing b < 6.

Front

What is the solution to the inequality x + 9 > 21?

Back

x > 12.

Front

How do you represent the solution x ≤ 10 on a number line?

Back

Draw a closed circle at 10 and shade to the left.

Front

What is the solution to the inequality -4x + 14 ≤ 54?

Back

x ≥ -10.

Front

If x = 15, is it a solution for the inequality x + 9 > 21?

Back

Yes, because 15 + 9 = 24, which is greater than 21.

Front

What does it mean if an inequality has no solution?

Back

It means there are no values that satisfy the inequality.
