The set of all integers is denoted by what letter? Z The set of all integers z is what type of set? Infinite ⊆ Has more or is equal to ∈ THE MEMBER OF/BELONGS TO If p is an integer, what can be said about 2p? (a) 2p is an odd number (b) 2p is an even number (b) 2p is an even numberExplanaiton: p ∈ Z, so 2p is an even integer. Even if p is a neg/pos# when mult by two it becomes even. ex: 2(7)=14 2(15)=30 2(4)=8. Also zero is neither negative or positive so dont worry about 2(0) because the question only asked if it would be neg/pos AuthorNayja ID165119 Card SetMath DescriptionCompass Test Review Updated2012-08-06T14:12:51Z Show Answers
