$\text{a) a solution }\\\text{b) a solution }\\\text{c) a solution }$
$\bf{\text{Solution Outline:}}$ Use the position of the number on the number line to evaluate if it satisfies the given inequality, $c\ge-7 .$ $\bf{\text{Solution Details:}}$ The inequality $c\ge-7$ is satisfied by all numbers that appear on/on the right of $-7$ in the number line. a) In the number line, $0$ appears on the $\text{ right }$ of $-7 .$ Hence, it is $\text{ a solution .}$ b) In the number line, $-5\dfrac{4}{5}$ appears on the $\text{ right }$ of $-7 .$ Hence, it is $\text{ a solution .}$ C) In the number line, $1\dfrac{1}{3}$ appears on the $\text{ right }$ of $-7 .$ Hence, it is $\text{ a solution .}$ Therefore, \begin{array}{l}\require{cancel} \text{a) a solution }\\\text{b) a solution }\\\text{c) a solution } .\end{array}
