Match the following inequalities to the correct interval notation:

A.) $\displaystyle {x}<-{3}$

\displaystyle {\left(-\infty,-{3}\right]}

\displaystyle {\left(-\infty,-{3}\right)}

\displaystyle {\left[-{3},\infty\right)}

\displaystyle {\left(-{3},\infty\right)}

B.) $\displaystyle {x}\ge-{1}$

\displaystyle {\left(-\infty,-{1}\right)}

\displaystyle {\left(-{1},\infty\right)}

\displaystyle {\left(-\infty,-{1}\right]}

\displaystyle {\left[-{1},\infty\right)}

C.) $\displaystyle {x}\le{7}$

\displaystyle {\left(-\infty,{7}\right)}

\displaystyle {\left(-\infty,{7}\right]}

\displaystyle {\left({7},\infty\right)}

\displaystyle {\left[{7},\infty\right)}

D.) $\displaystyle {x}>{1}$

\displaystyle {\left(-\infty,{1}\right]}

\displaystyle {\left({1},\infty\right)}

\displaystyle {\left(-\infty,{1}\right)}

\displaystyle {\left[{1},\infty\right)}
