The number line shows the elevation of the bottom of a harbor and the elevation of a fish swimming close to the surface. A vertical number line labeled "Elevation (m)" goes from –12 to 2 by twos. Zero is labeled "sea level." There is a mark at negative 1.5 labeled "–1.5 meters" with an icon of a fish and another mark at negative 10.5 labeled "–10.5 meters bottom

What change in elevation is necessary for the fish to reach the bottom?

Ihonestly have no clue if it's each or none.

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

Which function in vertex form is equivalent to f(x) = x2 + 6x + 3? f(x) = (x + 3)2 + 3 f(x) = (x + 3)2 − 6 f(x) = (x + 6)2 + 3 f(x) = (x + 6)2 − 6
