Unformatted text preview: properties of inequalities provide a way to transform one
inequality into an equivalent inequality.
Example
Solve the inequalities.
1 −5(x + 2) − 3 < 3x + 11. 2 9(w − 1) − 3w ≥ −2(5 − 3w ) + 1. Outline Inequalities Properties of Inequalities Compound Inequalities Applications Unions and Intersections of Sets Deﬁnition
Let A and B be sets.
1 The union of A and B is the set A ∪ B consisting of elements
a such that a ∈ A or a ∈ B . 2 The intersection of A and B is the set A ∩ B consisting of
elements a such that a ∈ A and a ∈ B . Example
Find the union and intersection of the sets
A = {−3, −2, −1, 0, 1, 2, 3, 4} and B = {−4, −2, 0, 2, 4}. Outline Inequalities Properties of Inequalities Compound Inequalities Applications Solving Compound Inequalities
