Beth is solving this equation: 1/x + 3 = 3/x She says “I can multiply both sides by x and get the linear equation 1 + 3x = 3, whose solution is x = 2/3.”

Which of the following statements makes this a correct argument, or shows that it is incorrect? Select all that apply.

A). The equation is not linear, so you cannot use the methods normally used for solving linear equations.

B). You can assume x ≠ 0 because both sides are undefined if x = 0.

C). After multiplying both sides by x you need to subtract 1 from both sides.

D). You cannot multiply both sides by x because you do not know what x is.

Which graph corresponds to the function f(x) = x2 + 4x – 1?

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
