A box company completed a study to determine the number of boxes an old machine would produce in an hour. They determined that the old machine produced 280 boxes in 4 hours.
During its first day of operation, a new machine, after running a full 8 hours, produced 56 more boxes than the old machine would have produced in that time.
Which of the following is true about the new machine

Best ResponseYou've already chosen the best response.0The equation y = 77x represents the production rate of the new machine The equation y = 84x represents the production rate of the new machine. The new machine can produce 14 boxes an hour. The new machine can produce 7 more boxes an hour than the old machine

Best ResponseYou've already chosen the best response.1the working rate R_1 of the first machine is: \[{R_1} = \frac{{280}}{4}\]

Best ResponseYou've already chosen the best response.0r u talking about the slope

Best ResponseYou've already chosen the best response.1more precisely \[{R_1} = \frac{{280}}{4} = 70\]

Best ResponseYou've already chosen the best response.1so after 8 hours, the first machine produces: 70*8=560 boxes

Best ResponseYou've already chosen the best response.1whereas the secon machine, produces: 560+56=616 boxes then the working rate R_2 of the second machine is: \[{R_2} = \frac{{616}}{8} = 77\]

Best ResponseYou've already chosen the best response.1namely: \[{R_2} = {R_1} + 7\]
