PLEASE help me! The graph below is represented by which system of inequalities? (look at picture) answer choices: x + y > 1 and 2x + y > 4 x + y < 1 and 2x + y > 4 x + y < 1 and 2x + y < 4 x + y > 1 and 2x + y < 4

ganeshie8 (ganeshie8):

hint- both are shaded up

OpenStudy (anonymous):

I think its x + y < 1 and 2x + y < 4, but i'm not for sure. @ganeshie8

ganeshie8 (ganeshie8):

its the reverse, if its shaded up, it means both inequalities are ">"

OpenStudy (anonymous):

x + y > 1 and 2x + y > 4, so that's the answer? I thought it was the opposite lol @ganeshie8

ganeshie8 (ganeshie8):

wait a sec.. . sorry im wrong... both are not shaded up... let me check again

OpenStudy (anonymous):

I'm so confused :( @ganeshie8

ganeshie8 (ganeshie8):

lets go step by step :) one line cuts x axis at "1" another line cuts x axis at "2"

OpenStudy (anonymous):

alrightt, so what now? @ganeshie8

ganeshie8 (ganeshie8):

the line that x axis cuts at "1", is shaded up(>) the line that cuts x axis at "2" is shaded down (<)

ganeshie8 (ganeshie8):

thats why we got that overlapping green region. ok ?

OpenStudy (anonymous):

So we are left with x + y > 1 and 2x + y < 4 ??? @ganeshie8

ganeshie8 (ganeshie8):

yo im here only... u dont have to mention me @... :)

OpenStudy (anonymous):

Lol soooooorrry bro

ganeshie8 (ganeshie8):

you're right... one is >, and another < lets see..

ganeshie8 (ganeshie8):

lol its okay... :)

ganeshie8 (ganeshie8):

so, we are left with two actually 2nd, and 4th options

OpenStudy (anonymous):

so how would i figure out which one is the answer?

ganeshie8 (ganeshie8):

its the last one, x + y > 1 and 2x + y < 4

ganeshie8 (ganeshie8):

if you see in the graph, the line with x intercept of 1, is shaded up!! so x+y > 1 is that inequality. simple.

I have another question similar to this one, i think. and i need help with it. I'm going to post it now lol thanks for your help
