Question

㏒₀,₃(3x-9)≤ ㏒₀,₃(4x-11)

Answer 1

$log _{0.3}(3x-9) leq log _{0.3}(4x-11)$

ОДЗ:
$left { {{3x-9 textgreater 0} atop {4x-11 textgreater 0}} right. to left { {{3x textgreater 9} atop {4x textgreater 11}} right. to left { {{x textgreater 3} atop {x textgreater 2.75}} right.$

$x in (3; +infty )$

$3x-9 geq 4x-11 \ 3x-4x geq -11+9 \ -x geq -2 \ x leq 2$
