    swap the coefficients.. I have no idea why that works but it does haha! I couldn't understand why i was getting past paper questions wrong.
    D1 exam tomorrow, thanks for the help!

      D1 exam tmw too, I can't seem to understand some of the things that I get wrong either. Any other revision type material you could share?

    How do you draw the profit line if given P= -x+y?

    What do you do when you have a negative coefficient?

    i dont get how did u get 1 and 3 for x and y?

  • @adilc4587
    @adilc4587 11 лет назад

    you do it by making x = to the maximum or minimum number

    is the point always at the intersection of two restraints?

    Hi, i'm doing the AQA paper on friday, i just need some help on the objective line. As you've said that you need to swap the coefficient and times it by a suitable number, but what if you have a minus. for example, on one off the AQA question, it has p=-x+y ~~~~~~one the graph provided, i can't do a minus as it will go off the graph so how will you do this. thankss

    Hi, instead of doing all this line crap with the ruler can i just not do simultaneous equations to the 2 intersecting lines, find the X and Y values then put it into the objective fucntion and maximise/minimise depending on the question?

    • @mikskywalker
      @mikskywalker 10 лет назад +1

      The crap with the ruler tells you which two intersecting lines to deal with. Sometimes it's quite hard to tell without it.

      Just learn the ruler method. I ended up getting an A on my D1 exam.

      +Slender Man It also allows you to work out maximised integer values if the given question is for a practical use. For example, the number of cartons of milk needed to make cake - you cant have 2.6.
