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

'≥' means 'greater than or equal to'.

Front

What does the symbol '<' mean?

Back

'<'' means 'less than'.

Front

How do you solve the inequality 32 ≥ 16p?

Back

Divide both sides by 16 to get p ≤ 2.

Front

What is the solution to the inequality 3x + 7 < 22?

Back

x < 5.

Front

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

Back

An open circle is used.

Front

Is x=15 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 can satisfy the inequality.

Front

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

Back

A closed circle indicates that the number is included (≤ or ≥), while an open circle indicates that the number is not included (< or >).

Front

How do you graph the inequality x > 3?

Back

Draw a number line, place an open circle at 3, and shade to the right.
