Answer
Draw an open circle on 12 and draw the line to the right
Draw a closed circle on 7 and draw the line to the left
Work Step by Step
$m\leq7$ means that all real numbers for the value of t are less than or equal to 7. Since m=7 is a solution, draw a closed circle on 7, draw the line to the left.
$m\lt12$ means that all real numbers for the value of m are greater than 12. Since 12 is not part of the solution set, draw an open circle on 12 and draw the line to the right.
