Answer
$\le$
Work Step by Step
$\bf{\text{Solution Outline:}}$
Use the properties of inequality to solve the given inequality, $
-7t\ge56
.$ Use the resulting solution to complete the relationship of $
t
\text{ and }
-8
.$
$\bf{\text{Solution Details:}}$
Dividing both sides by a negative number (and consequently reversing the inequality symbol)
\begin{array}{l}\require{cancel}
-7t\ge56
\\\\
\dfrac{-7t}{-7}\ge\dfrac{56}{-7}
\\\\
t\le-8
.\end{array}
Hence, the symbol that completes the relationship of $
t
$ and $
-8
$ is $"
\le
