What is an inequality in algebra?
Inequality, In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
What are the symbols for inequalities?
These inequality symbols are: less than (<), greater than (>), less than or equal (≤), greater than or equal (≥) and the not equal symbol (≠).
What are the four types of inequalities?
There are five systems or types of social inequality: wealth inequality, treatment and responsibility inequality, political inequality, life inequality, and membership inequality.
How do you describe inequalities?
An inequality is a mathematical statement that compares two expressions using the ideas of greater than or less than. … When you read an inequality, read it from left to right—just like reading text on a page. In algebra, inequalities are used to describe large sets of solutions.
How do you write an inequality with two variables?
To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality. If given a strict inequality, use a dashed line for the boundary. If given an inclusive inequality, use a solid line. Next, choose a test point not on the boundary.
What is an inequality sentence?
An inequality is a mathematical sentence that compares expressions. It contains the symbols <, >, ≤, or ≥.
How do you write the equation of an inequality?
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation the two expressions are deemed equal which is shown by the symbol =….Composing equations and inequalities.x>yx is greater than yx≥yx is greater than or equal to yx
How do you know when to use an inequality or an equation?
An equation or an inequality that contains at least one variable is called an open sentence. When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the equation or inequality.
How do you write an inequality word problem?

What is an inequality example?
For example, to solve -3x is less than 12, divide both sides by -3, to get x is greater than -4. And when graphing an inequality on a number line, less than or greater than is shown with an open dot, and less than or equal to or greater than or equal to is shown with a closed dot.
