r u sure about the question ?

OpenStudy (anonymous):

to know which inequality is true substitute the values of x and y in the inequality if it give true statements the inequality is true

OpenStudy (anonymous):

@eoog

OpenStudy (anonymous):

So only the first one is true then?

OpenStudy (anonymous):

can both of them be true ? or u have to choose one ?

OpenStudy (anonymous):

They both can be true

OpenStudy (anonymous):

I also had x<3 and y>2/3x-6 to choose from which are also true

OpenStudy (anonymous):

So second guessed myself if all 4 options were true

OpenStudy (anonymous):

x=2, y=-2 \[y \ge-4x \] \[-2\ge-4(2)\] \[-2\ge-8\] which is true

OpenStudy (anonymous):

that's the first one it's true

OpenStudy (anonymous):

the second one is\[y \le2x-4\] \[-2\le2(2)-4\] \[-2\le4-4\] \[-2\le0\] which is also true

OpenStudy (anonymous):

the third one is x<3 \[2<3\]

OpenStudy (anonymous):

also true

OpenStudy (anonymous):

the fourth one is \[ y >\frac{ 2 }{ 3x-6 }\] \[-2>\frac{ 2 }{ 3(2)-6 }\] \[-2>\frac{ 2 }{ 6-6 }\] -2>2/0 that's not true

OpenStudy (anonymous):

@eoog

OpenStudy (anonymous):

Are you sure? It's not written like that does that make a difference? It's written like \[y>\frac{ 2 }{ 3 } x-6\]

OpenStudy (anonymous):

oh off course it does make difference sorry didn't know what did u mean

OpenStudy (anonymous):

So all of them would be correct then?

OpenStudy (anonymous):

\[y >\frac{ 2 }{ 3 }x-6\] \[-2>\frac{ 2 }{ 3 }(2)-6\] \[-2>\frac{ 4 }{ 3 }-6\] \[-2>\frac{ 4-18 }{ 3}\] \[-2>\frac{ -14 }{ 3 }\] -14/3=-4.66 so \[-2>-4.66\] also true

OpenStudy (anonymous):

Thank you :)

OpenStudy (anonymous):

@ikram002p can u check this ?

OpenStudy (anonymous):

no problem :)

OpenStudy (anonymous):

bcoz all of the choices are true

OpenStudy (ikram002p):

ya ur right all of them r true :o

OpenStudy (ikram002p):

and its not an problem cuz it asked abt EVERY INEQUALITY OF WHICH IS A SOLUTION

OpenStudy (anonymous):

@ikram002p thanks alot :)

np :D
