The solution to this compound inequality is $\displaystyle{m}<-{4}\usepackage{cmbright}\Huge\$ and $\displaystyle{m}\le-{3}\usepackage{cmbright}\Huge\$ . Their graphs intersect for $\displaystyle{m}<-{4}\usepackage{cmbright}\Huge\$ , so any value less than $\displaystyle-{4}\usepackage{cmbright}\Huge\$ is a solution.
