What set of coordinates satisfies the equations 3x- 2y = 15 and 4x - y =20?

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
