Question 30183
i am not sure waht you mean...you have written something that is ambiguous.


You could mean {{{ (-1/(8k)) > -1 }}} in which case we have:
{{{ (-1/8) > -k }}}
or {{{ -k < (-1/8) }}}. Now divide by -1
and hence {{{ k > 1/8 }}}


or you meant {{{ (-1/8)k > -1 }}} in which case we have:
{{{ -k > -8 }}}. Now divide by -1
and hence {{{ k < 8 }}}


Both situations use the same rules, namely if you multiply or divide by a negative number, the inequality sign  swaps round.
