Harry’s soccer team plays 2 nonconference games for every 3 games that they play against conference opponents. if y represents the number of nonconference games and x represents the number of conference games, which equation best models this proportional relationship? a)y=2/3 x b)y=3/2 x c)y = 2x d)y = 6x

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

What is the difference between the predicted value and the actual value
