OpenStudy (anonymous):

do you have any ideas?

OpenStudy (anonymous):

x < -1/2 or x > 7/2

OpenStudy (anonymous):

you must change 'x' to some number 0 2 3 4

OpenStudy (anonymous):

dnt no how

OpenStudy (anonymous):

|4 * 0 - 6| > 8 ????

OpenStudy (anonymous):

|4 * 2 - 6| > 8?? |4*3-6|>8 ? |4*4-6|>8 ???

OpenStudy (anonymous):

no thats not how it works

OpenStudy (anonymous):

im confused

OpenStudy (anonymous):

answer "D" not correct ???

@StudyGuidance

OpenStudy (welshfella):

you need to solve 4x - 6 > 8

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

im getting so confused about wat i am supposed to do now

OpenStudy (welshfella):

solve that inequality you'll get x > some number then pick the option which is greater than that number

OpenStudy (anonymous):

|4x-6>8 4x-6<-8 or 4x-6>8 4x-6<-8 :x<-1/2 4x-6>8 :x>7/2

OpenStudy (anonymous):

thats wat i got which is not rite

OpenStudy (welshfella):

yes it is which of the options is a number greater than 7/2 (3.5) ?

OpenStudy (anonymous):

so my answer wld be C. 3

OpenStudy (welshfella):

No - the answer is a number GREATER than 3.5

OpenStudy (welshfella):

any number greater than 3.5 would be a solution but there is only one option to fit the bill

OpenStudy (anonymous):

omg. so im gonna put 3

OpenStudy (welshfella):

no 3 is wrong - 3 is not greater than 3.5 which one is?

OpenStudy (anonymous):

so its d. 4

OpenStudy (welshfella):

yes

OpenStudy (welshfella):

4 is the only option greater than 3.5
