The solution to this compound inequality is $\displaystyle{m}\ge-{4}\usepackage{cmbright}\Huge\$ and $\displaystyle{m}>-{9}\usepackage{cmbright}\Huge\$ . Their graphs intersect for $\displaystyle{m}\ge-{4}\usepackage{cmbright}\Huge\$ , so any value greater than or equal to $\displaystyle-{4}\usepackage{cmbright}\Huge\$ is a solution.
