Example: Solving and Graphing
To solve the linear inequality , the Addition Property of Inequality is used. First, add to both sides of the inequality to isolate the variable. The resulting statement simplifies to . To graph this solution set on a number line, a right bracket is placed at to indicate the endpoint is included, and the number line is shaded to the left. In interval notation, the solution is expressed as .

Learn After
A logistics coordinator is monitoring the total weight of a shipment, represented by the variable . After a standard weight reduction of tons for packaging, the remaining weight must not exceed the loading limit of tons. This requirement is modeled by the inequality , which simplifies to . Which of the following correctly represents this solution in interval notation?
An engineering assistant is modeling a tolerance limit using the inequality , where represents the allowable deviation. Arrange the following steps in the correct order to solve the inequality and represent the solution graphically and in interval notation.
A warehouse manager is using the inequality to monitor the allowable weight variance (in tons) for a cargo shipment. To prepare a safety compliance report, match each mathematical component of the solution with its correct functional description.
A quality control technician at a manufacturing plant is checking a component's tolerance using the inequality . True or False: To isolate the variable and solve the inequality, the technician should apply the Addition Property of Inequality by adding \frac{3}{8} to both sides.
Interval Notation for Logistics Variance Reports
A supply chain trainee is reviewing a standard operating procedure document that uses the linear inequality to model acceptable delivery time variances. The document notes that after simplifying the inequality to , the solution is graphed on a number line by shading to the left and placing a right ________ at to indicate that the endpoint is included.
