Shane biked 1 mile less than three times the number of miles lissette biked. shane biked a total of 7 miles. write an equation to determine how many miles lissette biked. 7 = 3x − 1 x − 1 = 3(7) x over seven = 3(1) 7 + 3x = 1

Fred and gene are hang gliding. fred is 700 feet above the ground and descending at 15 ft/s. gene is decending as shown in the table. interpret the rates of change and initial values of the linear functions in terms of the situations they model. show all work. freds equation is f(x)=-15x+700. ( genes is the table attached)
