Can someone please help me with precalc? Can you just explain it to me please? In the lesson it said nothing about this, but I am sure it's easy, I just really don't understand. Please Help
Use the graph below to show which numbered region belong to the graph of the solution set of each system of questions.

Best ResponseYou've already chosen the best response.0first, identify the lines, ingnoring the inequality. line in #2, identify the line x =0 and the line y = x

Best ResponseYou've already chosen the best response.0correct and it divides the plane into 2 regions... which region satisfies the inequality x>= 0?

Best ResponseYou've already chosen the best response.0hmm, if it was > or = to wouldn't that mean that it would be shaded on the right side?

Best ResponseYou've already chosen the best response.0hmm, I believe it would be on the right side of the line y=x? Since it is < or = to?

Best ResponseYou've already chosen the best response.0Ok thank you, yes it does. So to answer that I would need to put it into a (x, y) form?

Best ResponseYou've already chosen the best response.0no, look at the question... it's asking what region or regions belong to the solution set. the regions are numbered so you must provide all of the numbers that relate to the proper region(s). what number(s) are valid?

anonymous

Best ResponseYou've already chosen the best response.0any point within the region or regions must satisfy both inequalities.

Best ResponseYou've already chosen the best response.0Oh ok, sorry. So for that I would need to pick a plot and put it into the inequalities like an equation?

Best ResponseYou've already chosen the best response.0no... look at your link! see the numbers on the graph? what shape does number 5 pertain to?

anonymous

Best ResponseYou've already chosen the best response.0ok, looking. So all of the numbers would have to satisfy both and the ones pictured in the original graph?

Best ResponseYou've already chosen the best response.0dw:1441218845167:dwoops, this is the region represented by 5

anonymous

Best ResponseYou've already chosen the best response.0Ok so it would be all the points inside that section that would represent the region(s)?

Best ResponseYou've already chosen the best response.0yes. is region 5 in the solution set?

anonymous

Best ResponseYou've already chosen the best response.0No, I am not sure. Would it have to be something like x=5 or in that format? Or would I just simply list region 5? Sorry trying to make sure I understand the whole process.

Best ResponseYou've already chosen the best response.0region 5 represents an infinity of points... you are only supposed to list the numbers of the regions, separated by commas. you need to read and understand the question before you can hope to answer it with any confidence and understanding. the region number is a simple way of identifying all the points within that region. just like California identifies all the points on the globe that are within the region defined as California.

Best ResponseYou've already chosen the best response.0So it would simply be 5? Since it is talking about regions and everything within 5 as you were saying would satisfy the inequalities. I apologize, this is a fairly easy concept I am sure, I just am relatively turned around.

Best ResponseYou've already chosen the best response.0you have to list ALL regions that satisfy the inequalities, separated by a comma. is 5 the ONLY region that satisfies the inequality? if so, then just put 5. If not, then you will have to put 5 and thena comma and then the next number and so on... good luck!
