What is an inequality?

An inequality is a mathematical expression that shows a relationship between two values that are not equal, using symbols such as < (less than), > (greater than), ? (less than or equal to), ? (greater than or equal to) to represent the relationship. It indicates that one value is different from another, rather than being the same.

How is an inequality different from an equation?

An inequality differs from an equation because it shows a relationship between two expressions that are not necessarily equal, indicating a comparison of values that are either greater than, less than, greater than or equal to, or less than or equal to each other. In contrast, an equation shows a relationship between two expressions that are equal to each other.

What is the solution to an inequality?

The solution to an inequality is a set of values for the variable that make the inequality true. This set can be expressed using interval notation or set notation, depending on the context of the problem.

How do you graph an inequality on a number line?

To graph an inequality on a number line, first identify if the inequality is greater than, less than, greater than or equal to, or less than or equal to a certain number. Then, mark that number on the number line. If the inequality is greater than (>), mark an open circle on the number and shade to the right. If the inequality is less than (<), mark an open circle on the number and shade to the left. If the inequality is greater than or equal to (?) or less than or equal to (?), then use a closed circle and shade accordingly.

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

A strict inequality, denoted by < or >, indicates that the two quantities being compared are not equal and that one is strictly greater than or less than the other. On the other hand, a non-strict inequality, denoted by ? or ?, includes the possibility that the two quantities could be equal to each other. In summary, a strict inequality excludes the possibility of equality, while a non-strict inequality includes the possibility of equality.

How do you solve a one-variable inequality algebraically?

To solve a one-variable inequality algebraically, follow these steps: 1) Isolate the variable on one side of the inequality sign. 2) Perform the necessary operations to simplify the inequality. Remember to reverse the inequality sign if you multiply or divide by a negative number. 3) Write your final answer in interval notation or set notation, depending on the context of the problem. Double-check your solution by plugging it back into the original inequality to ensure it satisfies the given conditions.

How do you solve a compound inequality?

To solve a compound inequality, you must first simplify each inequality separately and then take into account the "and" or "or" connector between them. For "and" (meaning both inequalities must be true), find the overlap of the two solution sets. For "or" (meaning either inequality can be true), combine the two solution sets. Finally, express the solution in interval notation or on a number line to represent the range of values that satisfy the compound inequality.

What are absolute value inequalities?

Absolute value inequalities involve inequalities with absolute value expressions. These inequalities consist of two expressions separated by an inequality sign (<, ?, >, or ?) and involve absolute value symbols around variables or constants. When solving absolute value inequalities, it is essential to consider both positive and negative solutions for the variable and may require breaking the inequality into multiple cases to find all possible solutions.

What are interval notations?

Interval notations are a way to represent a set of real numbers with the use of parentheses or brackets. They are used to show the range of values in a continuous interval. For example, the interval notation (3, 8) represents all real numbers greater than 3 but less than 8, while the notation [1, 5] represents all real numbers greater than or equal to 1 and less than or equal to 5.

How can inequalities be used in real-world situations?

Inequalities are commonly used in real-world situations such as determining pricing strategies for products, setting limits on speed or weight restrictions in transportation, establishing eligibility criteria for loans or scholarships, and predicting outcomes in financial investments. They are also used in fields like engineering to ensure structural stability, in healthcare to assess risk factors for diseases, and in marketing to target specific customer segments. Ultimately, inequalities provide a quantitative framework to make decisions and solve problems across a wide range of industries and applications.
