Subtract the equations. 3x + 4y = 17 - (3x +2y = 2)

Which polynomial function has x intercepts -1, 0, and 2 and passes through the point (1, -6)

Pls! does anybody know a shortcut for answering these types of questions in the future?

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below.the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.
