Can anyone help me please

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

Find dy/dx using implicit differentiation ln(20+e^xy)=y

Write an expression that has three terms and simplifies to 4x - 7. identify the coefficient(s) and constant(s) in your expression
