help me with this graph inequalities!!!?

Question

20 >/ 2x+2y

20>/ xy

i need help on graphic these inequalities,,,
if u can't show me graphs... you can just tell me the points...
thank you!!!

Answer 1

Just graph these equations:

y <= 10 - x

y <= 20 / x

The trick is to solve each inequality for y and graph them. You should remember from class (or be able to tell from your book) how to shade the graph. It's too difficult to explain in text. Good night!

Answer 2

first either make equal to "y" or make "y" = to 0 and solve for "x" then make the "x" = to 0 and solve for "y". You want to use the second method with these equations. the first equation the point it goes through is (10,0) and (0,10). make the line a solid line because they are "lessthan or equal to" sign. you then need to shade the side that makes the equation true so you need to pick a point and plug it in to the equation and if it works then shade that side. try and figure out the second if not ask your teacher they will explain it and make u understand.
