AIM: How can we efficiently solve inequalities and use substitution to check solutions?
HW: Complete problem set below
Noah found the solution to the inequality below by using the following steps.
-4x+5>25 ----> -4x+5=25
(Graph open circle on -5, pointing to the right)
Do you agree with Noah?
Students examined 4 problems involving inequalities. They matched inequalities that modeled some real-world examples. They then analyzed the different parts of each inequality and what it represented. They solved the inequalities and interpreted what the solution meant in the context of the problem.
