$-12\lt t$
$-4\lt t+8\longrightarrow$ 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.
