5n-3(n-6) >= 0

OpenStudy (3mar):

Could I help you?

OpenStudy (hekaphage):

yes, please.

First distribute the `3` into the paranthesis `(n-6)`. \(\huge\bf{5n+(-3\times n +6 \times 3) \ge 0}\)

OpenStudy (hekaphage):

I got 5n-3n-18>=0 Would that be correct?

563blackghost (563blackghost):

Correct :) Though it would `+18` not `-18` Now combine like terms... \(\huge\bf{\color{red}{5n-3n}{+18\ge0}}\)

OpenStudy (hekaphage):

So would the answer be \[n \ge -9\]?

563blackghost (563blackghost):

Nice ;)

OpenStudy (hekaphage):

Thank you!

563blackghost (563blackghost):

No problem :)
