## Algebra 1: Common Core (15th Edition)

$c\lt8$ means that all real numbers for the value of c are less than 8. Since c does not equal 8 put an open circle on 8 and draw the line to the left. $c\geq10$ means that all real numbers for the value of c are greater than or equal to 10. Since c can equal 10, put a shaded/closed circle on 10 and draw a line to the right.
