Inequality and Sets

A = {x : x is a letter in the word SEAT}

B = {x : x is a letter in the word TASTE}

Determine if these two sets are equal or equivalent.

• Not equal because seat has 4 letters and taste has 5 letters.

• Equivalent because they have the same letters

• Equal because each set has the same cardinality and the same letters.

If every element in set A is also in set B, then...

• A is a subset of B

• B is a subset of A

• A = B

• A and B are disjoint

Which inequality is represented by the  following graph

• x < -8

• x > -8

• x ≥ -8

• x ≤ -8
