Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.

Use the elimination method to solve the systems of equations. choose the correct ordered pair. 7x+4y=39

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 5x^2 + 10x
