Linear Inequality Word Problems

What is a linear inequality?

Back

A linear inequality is a mathematical statement that compares a linear expression to a value using inequality symbols (such as <, >, ≤, or ≥). It represents a range of possible solutions rather than a single solution.

How do you represent a situation with a linear inequality?

Back

To represent a situation with a linear inequality, identify the variables, the coefficients, and the constraints. Formulate the inequality based on the relationships described in the problem.

What does the symbol ≤ mean in a linear inequality?

Back

The symbol ≤ means 'less than or equal to.' It indicates that the value on the left can be less than or equal to the value on the right.

What does the symbol ≥ mean in a linear inequality?

Back

The symbol ≥ means 'greater than or equal to.' It indicates that the value on the left can be greater than or equal to the value on the right.

How do you solve a linear inequality?

Back

To solve a linear inequality, isolate the variable on one side of the inequality sign, similar to solving an equation. Remember to reverse the inequality sign when multiplying or dividing by a negative number.

What is the difference between a strict inequality and a non-strict inequality?

Back

A strict inequality uses < or >, meaning the values cannot be equal. A non-strict inequality uses ≤ or ≥, allowing for equality.

What is the graphical representation of a linear inequality?

Back

The graphical representation of a linear inequality is a shaded region on one side of a boundary line. The line is solid for ≤ or ≥ and dashed for < or >.

How do you write an inequality for a budget constraint?

Back

Front

What does it mean if a linear inequality has no solution?

Back

If a linear inequality has no solution, it means that there are no values for the variables that satisfy the inequality. This often occurs when the constraints contradict each other.

Front

How do you interpret the solution set of a linear inequality?

Back

The solution set of a linear inequality includes all the values that satisfy the inequality. It can be represented as a range of numbers or as a shaded area on a graph.
