Which Represents the Solution Set of the Inequality? Unraveling the Enigma

Inequalities are mathematical expressions that represent relationships between two expressions. Determining the solution set of an inequality involves finding all the values that make the inequality true. The solution set can be represented in various forms, such as intervals, unions of intervals, or inequalities.

Understanding which represents the solution set of the inequality is essential for solving inequalities and applying them to real-world problems. For instance, in economics, inequalities can model budget constraints or resource allocations. In physics, they can describe the range of possible values for physical quantities, such as velocity or acceleration.

The solution set of an inequality can be represented in interval notation, which uses parentheses or brackets to indicate the endpoints of the interval and a comma to separate the endpoints. For example, the solution set of the inequality x > 3 can be represented as (3, ∞). Alternatively, it can be represented as an inequality, such as x ∈ R | x > 3, where R denotes the set of real numbers.

In summary, the solution set of an inequality represents all the values that make the inequality true. It can be represented in various forms, such as intervals, unions of intervals, or inequalities. By understanding which represents the solution set of an inequality, we can solve inequalities effectively and apply them to a wide range of fields.

Representing the Solution Set of Inequalities

Inequalities, mathematical expressions involving non-equality signs (<, >, ≤, ≥), represent regions or sets of points that satisfy the given condition. Graphically, these regions can be visualized as shaded areas on a number line or in a coordinate plane. Understanding the solution set of an inequality is crucial for various mathematical applications, including solving equations, optimization problems, and modeling real-world scenarios.

Linear Inequalities on the Number Line

The simplest form of inequalities involves linear expressions on a number line. For example, the inequality x < 5 represents all the numbers on the number line to the left of 5, excluding 5 itself. The solution set is denoted as (-∞, 5).

Linear Inequalities in the Coordinate Plane

Linear inequalities in the coordinate plane involve two variables and define regions of the plane that satisfy the inequality. The inequality y > 2x – 1, for instance, represents the region above the line y = 2x – 1.
