Graphing inequalities and interval notation
WebJan 24, 2024 · A system of inequalities is a set of two or more inequalities, depending on how many variables are in the inequalities (i.e., two variables, two inequalities). For example: {eq}2x + 3y > 6 {/eq} WebFeb 17, 2024 · Explanation: First, solve for x: − 5 3x ≤ − 10. When dividing or multiplying by a negative, then flip the inequality sign. ( − 5 3 ⋅ − 3 5)x ≤ − 10(− 3 5) x ≥ 6. To write interval notation, use brackets [] and parenthesis (). Brackets are used when the answer is included, and parenthesis are used when the answer is excluded.
