Graph the solution set of each system of inequalities or indicate that the system has no solution. −2≤x<5

검증된 단계별 안내

Identify the inequality given: \(-2 \leq x < 5\). This describes the range of \(x\) values that satisfy the inequality.

Understand that this inequality represents all \(x\) values starting from \(-2\) (inclusive) up to but not including \(5\) (exclusive).

On a number line, mark the point \(-2\) with a closed circle to indicate that \(x\) can be equal to \(-2\).

Mark the point \(5\) with an open circle to indicate that \(x\) cannot be equal to \(5\), but values less than \(5\) are included.

Shade the region on the number line between \(-2\) and \(5\) to represent all \(x\) values that satisfy the inequality \(-2 \leq x < 5\).

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Inequalities and Their Solution Sets

An inequality expresses a range of values that a variable can take. The solution set includes all values that satisfy the inequality. For example, −2 ≤ x < 5 means x can be any number from −2 up to but not including 5.

Graphing Inequalities on a Number Line

Graphing inequalities involves shading the portion of the number line that represents all solutions. Closed circles indicate inclusive boundaries (≤ or ≥), while open circles indicate exclusive boundaries (< or >). For −2 ≤ x < 5, use a closed circle at −2 and an open circle at 5.

Systems of Inequalities

A system of inequalities consists of two or more inequalities considered together. The solution set is the intersection of all individual solution sets. If no values satisfy all inequalities simultaneously, the system has no solution.
