how do i describe the solution region to the system {x-3y<3 x-3y>0

OpenStudy (anonymous):

help me somebody, please

ganeshie8 (ganeshie8):

did you graph the inequalities

OpenStudy (anonymous):

it doesnt tell me to

ganeshie8 (ganeshie8):

their slope is same. so you will get a parallelogram

ganeshie8 (ganeshie8):

yeah.. in order to describe the system, we need to visualize it right ?

OpenStudy (anonymous):

yes we do

ganeshie8 (ganeshie8):

the key here is : x-3y<3 ----(1) x-3y>0----(2) i would describe it in two statements as below : 1)both inequalities have same slope. and since the (1) is intersecting y axis at -1 and shaded up, and (2) is passing thru origin, the solution set forms a parallelogram. 2)

ganeshie8 (ganeshie8):

you need to actually graph the system to complete 2nd statement... ie, to describe any further

OpenStudy (anonymous):

okay thank yu
