C) Noah sets out on a road trip from Barrie to Kingston, a distance of 375 km. Noah drove at 100 km/h for part of the trip, and 75 km/h for the remainder of the trip. The trip took 4 h 15 min.
How far did he drive at each speed? (Linear Relations)

Write a real-world solution that can be represented by the equation y = 7x be sure to explain what the variables represented in the solution

Solve for x and y a x= 13.3 y= 16.7 b x= 23.3 y= 12.5 c x= 7.5 y= 16.7 d x=7.5 y= 12.5

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
