The balance of susu's savings account can be represented by the variable b. the inequality describing her balance b > $30 . which could be a solution to the inequality?

On a final exam, each multiple-choice question is worth 4 points and each word problem is worth 8 points. lorenzo needs at least 50 points on the final to earn a "b" in the class. which inequality represents x, the number of correct multiple-choice questions, and y, the number of correct word problems, he needs to earn a "b"? 4x + 8y < 50 4x + 8y s 50 4x + 8y > 50 4x + 8y 250

Here are the coordinates for eight points on the coordinate plane (q > p > 0): a (0, 0), b (p, 0), c (q, 0), d (p + q, 0), e (0, q), f (p, q), g (q, q), and h (p + q, q). which four points, if any, are on the vertices of a square?
