How can inequalities be used to represent relationships and solve problems?

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

How do i do this activity, is appreciated

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2
