Question

Test the following statement to see if it is reversible. If so, choose the true biconditional. If x = 3, then x^2 = 9. x = 3 if and only if x^2 = 9. x^2 = 9 if and only if x = 3. If x^2 = 9, then x = 3. This statement is not reversible.

Answer 1

The statement "If x = 3, then x^2 = 9" is true, but its converse "If x^2 = 9, then x = 3" is not true. Therefore, this statement is not reversible.

The true biconditional would be "x = 3 if and only if x^2 = 9."
