Linear inequality question ? I come up with: y > .50x + 4

[tathagata7]

Hi,

I need verification of answer for a linear inequality problem in my SSAT workbook:

0.25​

x

+ 4​

y

– 4 > 0.75​

x

+ 12 in terms of ​

y

the book has: y > .125x + 4

I come up with: y > .50x + 4
Other thoughts?

Thanks,

Carrie

The SSAT book has y > .125x + 4 as the answer.

I come up with y > .50x + 4

Thoughts?

Thanks,

If your problem statement:

0.25 * x + 4 * y - 4 > 0.75 * x + 12

Express in terms of 'y'

- then the book answer is correct.

I cannot tell where you slipped - because you did not show any work.

I suspect that you forgot

0.5/4 = 0.125

Got it! thanks

I forgot to divided .5x/4 I just divided 16/4 in the below equation stage

4y > .5x + 16
