Suppose your grades on four science exams are 99, 86, 76, and 95. what grade do you need on your next exam to have a 91 average on the five exams? a. 89.4 b. 93 c. 90 d. 99

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

6x + 3y = -6 2x + y = -2 a. x = 0, y = -2 b. infinite solutions c. x = -1, y = 0 d. no solution

Which statements describe the solutions to the inequality x< -20 check all that apply. there are infinite solutions. each solution is negative. each solution is positive. the solutions are both positive and negative. the solutions contain only integer values. the solutions contain rational number values.
