You do realize that without the system of inequalities we can't even begin to help you right?
I need help makin the system of inequalities i have no idea how to make them
http://www.purplemath.com/modules/syslneq.htm Tell me if this helps.
I just need to know how to make a system of inequalities for a 10 x 10 graph i am really confused now :\
Read it, it helps.
Hey, did you read the link?
I read it and i am more confused :( i just need to know how to make a inequalitie for my graph ....................
inequalities define an area bordered by a line or curve.
write an equation: then change the = sign to either > or <
how do i writ a equasion? sorry guys i know nothing about this subject :(
usually by making up something to put on the left side of an equals sign; and something to equate it to on the right side of an equals sign: y = 2x + 1 is an equation z = cos(x) + tan(x+y) is an equation etc ....
so if my graph is 10 by 10 my equation can be y=-4+3? that is just one
it can be yes, or simplify that to y = -1
then change the equal sign to either > or < to make it an inequality
!!! ok!!! thank u now i know what to do!
good luck :)
|dw:1333118992075:dw|one more question if this is my inqualtie y>4+1 and this is my graph how would i shade it?
^^^^ yes i know it is crapy :p
ok, your line (make it dotted, or change to an >=) is at y = 5|dw:1333119582201:dw| the shade is the area that makes the inequality true, so we have to pick a point that is clearly on one side of the line or the other to check with. This should make sense since we are not wanting to test the line, but an area on one side of it. the simplest point to choose for this test is (0,0) y>5 ; 0>5 is a lie; so we want all the point on the other side of the line; by icking all those point on that side we "fill in" that area and it becomes shaded.
might i suggest we make a sloping line tho? y > 4x+2 might fit within the graphing window easier
since 0 > 4(0)+2 is a lie, we want the true side shaded|dw:1333119931939:dw|
HAHA :P ok thanks again!
