The graph shows the relationship between time and the number of soda bottles a machine can make. use the points (4,80) and (7,140) to find the number of soda bottles the machine can make each minute.

1200

Step-by-step explanation:

We can gather from what's given that y=20x

y represents the total number of bottles produced in the given time in seconds, which is x. When x=1, y=20, This means that each second the machine can make 20 soda bottles. Each minute is 60 seconds, so when x=60, y=20*60 =1200 soda bottles.

y(300)=10x+50

Step-by-step explanation: we know that Y has to be 300 because that is our final amount of money that we have paid. we pay 10 bucks a month for the membership alone. the initail fee is 50 bucks so what you start with. we then can start plugging in numbers to solve for x. if you do x=25 you will get 300.

10(25)+50=300

   250+50=300

therefore your equation will be Y=10x+50
