#### Answer

$-12\lt t$

#### Work Step by Step

$-4\lt t+8\longrightarrow$ subtract 8 from each side
$-4-8\lt t+8-8\longrightarrow$ subtract
$-12\lt t$
An open dot will show that -12 is not included in the solution set.
Since the variable is greater than the endpoint, the arrow will continue to the right in the direction of increasing value.
