Delete AC and focus on the intersection of AB and BC. Keeping points B and C fixed, move point A to different locations and observe how ZABC changes. What must you do to increase or decrease m ABC ? What happens if you move point A

to a location directly on CB? What is mABC at this location? Explain

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.
