Do Now Aim # 17: How Do We Solve and graph basic Inequalities? When x = ―3, is the following statement true? No! Check: X
Minilesson: What is an “Inequality?” Any mathematical statement other than “is equal to.”
Minilesson: ≠ “is not equal to” “is never equal to” “cannot be equal to”
Minilesson: > “is greater than” “is more than” “must be greater than”
Minilesson: < “is less than” “must be less than”
Minilesson: ≤ “is less than or equal to” “is at most” “is no more than”
Minilesson: ≥ “is greater than or equal to” “is at least” “is no less than”
Minilesson: notice something important: is less than
Minilesson: notice something important: The means it is NOT subtraction! is
Minilesson: Ex: “Ten less than a number is less than 45.” TRANSLATES TO . . .
Minilesson: Solving an inequality is just like solving an equation.
Minilesson: Graphing the solution to an inequality represents all the real numbers that make the inequality true.
