Question 4 • AZ-Common Core Algebra II A

If p ↔ q is true, which compound statement has the same truth value?

Answer
A
p → q is false and q → p is true.
B
p → q is false and q → p is false.
C
p → q is true and q → p is false.
D
p → q is true and q → p is true.

Explanation

A biconditional, p ↔ q, is true when p and q have the same truth value. In that case, each implication is true: p → q and q → p. So the matching statement is “p → q is true and q → p is true.”
