A construction crew is lengthening a road. The road started with a length of 52 miles, and the crew is adding one miles to the road each day. Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write equation relating L to D . Then use this equation to find the total length of the road after the crew has worked 26 days.

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.
