During an intramural basketball game, team a scored 12 fewer points than team b. together, both teams scored a total of 150 points. how many points did team a score during the game? 75 points 81 points 70 points 69 points

Team A: x - 12

Team B: x

Team A + Team B = Total Points

 x - 12   +     x        =        150

                  2x - 12 = 150

                          2x = 162

                            x = 81

Team A: x - 12   = (81) - 12   = 69

69 points

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
