19.) the number of baby boomers has been decreasing and the number of millennials has been increasing. now millenials have surpassed boomers in number. the following equations approximate the population y (in millions) of the given generation in year x, where x = 14 corresponds to the year 2014. (data from: pew research center.)
boomers: 10x+13y = 1125 millenials: -2x+7y = 495

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
