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

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
