Which expression is equivalent to \large -\frac{1}{2}\left(\frac{1}{4}x-\fra c{3}{8}\right)? a \large -\frac{1}{8}x+\frac{3}{16} b \large -\frac{1}{8}x+\frac{3}{8} c \large \frac{1}{8}x-\frac{3}{16} d \large \frac{1}{8}x-\frac{3}{8}

Is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis.

What is always true when two whole numbers are subtracted?

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
