Mathematics — first biennium · Lesson
Solving a system of inequalities means intersecting the solution sets, not taking their union.
Prerequisites: Linear inequalities
Goal: Intersect solution sets of several linear inequalities.
In this lesson: Intersect solution sets of several linear inequalities.
How to proceed: Picture the two rays and keep only the overlapping part: a system requires both inequalities to be true.
You can already assume: Linear inequalities.

Data / situation: x>-5 and x≤-2
ConceptStep separates what is required from what is recommended or useful as reinforcement. Only required prerequisites block your progress.
Relationships: solid line = required · dashed line = recommended · dotted line = reinforcement.
