Which graph correctly solves the system of equations below? y = − x2 + 1 y = x2 − 4
a) quadratic graph opening up and quadratic graph opening down. they do not intersect.
b) quadratic graph opening up and quadratic graph facing down. they intersect at negative 2, negative 3 and 2, negative 3.
c) two intercepting parabolas are shown, one facing downward and one facing upward. the downward facing parabola has a maximum at (0,1) and intercepts the x axis at 1 and negative 1. the upward facing parabola has a minimum at (0,-4) and intercepts the x axis at 2 and negative 2
d) two quadratic graphs opening up. they intersect at 0, negative 4.

Simplify 15(x - 4)(x -1)-3(x + 4)(x - 1) with steps

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
