Flashcardizz Activity - Lesson 4.7 Inequalities (Part 1)

Front

What is an inequality?

Back

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

Front

What does the symbol '>' mean?

Back

The symbol '>' means 'greater than'. For example, 5 > 3 means 5 is greater than 3.

Front

What does the symbol '<' mean?

Back

The symbol '<' means 'less than'. For example, 2 < 4 means 2 is less than 4.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'. For example, 7 ≥ 7 means 7 is greater than or equal to 7.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'. For example, 3 ≤ 5 means 3 is less than or equal to 5.

Front

How can inequalities be represented graphically?

Back

Inequalities can be graphed on a number line, showing the range of values that satisfy the inequality.

Front

What is the difference between 'x > -2' and '-2 < x'?

Back

There is no difference; both mean the same thing: x is greater than -2.

Front

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

Back

The solution set includes all numbers less than 4, represented on a number line with an open circle at 4.

Front

How do you read the inequality '11 ≤ a'?

Back

It means 'a is greater than or equal to 11'.

Front

What is a true statement about inequalities?

Back

If a < b and b < c, then a < c is a true statement (transitive property of inequalities).
