Abby took an after-school job as a checker at petco. she stocks 9 large bags of cat food per hour and there are already 7 large bags on the shelf when she started working. write a function rule for the number of customers abby has checked out after 'x' hours.

y= 9x +7

Step-by-step explanation:

What she starts with is 7 bags.  That is the y intercept  ( or 0 hours)

The rate is 9 bags per hour  ( That is the slope)

y = mx+b, where m is the slope and b is the y intercept

y is how many bad on the shelf after x hours

y= 9x +7

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
