2 train-lines leave the same central station at the same time.(adsbygoogle = window.adsbygoogle || []).push({});

line 1: [itex]f(x) = 6000 + 50x[/itex]

line 2: [itex]g(y) = 2000 + 50y[/itex]

x and y are the number of departures pr. hour. line 1 can have 2 departures pr. hour pr. trian, and line 2 can only have 1 departure pr. hour pr. train.

There is a total of 100 trains.

I'm supposed to show this graphically.

I have:

[itex]x + y \geq 100[/itex]

Since line 1 can have 2 departures pr. hour. pr. train, I also have:

[itex]f(x) = 6000 + 50(2)x[/itex]

But, I'm confused on how I show this graphically? What do I need to plot here?

Plotting f(x) and g(y) doesn't make any sense at all.
