LP 2d Graphs And Formuating , Flashcards
If they say in the time she has, this is a new variable, as we don’t know this varibale quantity what quantity can we give it’s
Total time = 1
Thus if in total time she can make 40a, how long takes to make 1a?
And if some combination I’m herr time , what will this be
A/40
All the times for 1 x the amount must add to be less than equal to the total time, so 1
Less than bevause might be better for her not to use ALL HER TIME
A/40 + b/30 +x/10 <= 1!
How to convert from 3 to 2 variable
What to do with = sign after?
Hopefully there is an inequality that is an = sign
In this case, use this inequality to substitute for the rest, AND THEN IGNORE THIS INEQUALITY LATER DONT NEED IT
If in maximise or minise objective function there is a number, can we ignore it?
Yes can ignore it, or introduce a new varibale that takes care of the nunber
MUST IGNORE IT, just put it in brackets
DOMT FROGET NON NEGATIVITY CONSTRAINTS IF ORIGIN IS PART OF THE THING !!!
Don’t lack, question asked for and you forgot
