When graphing inequalities, which symbols have an OPEN circle?
< Less Than
> Greater Than
True or False? If graphing x < 5, we would put an open circle on 5 and shade to the right.
False.
Solve and graph
4x + 3 < 7
x < 1
Solve and graph
x + 5 > 12 OR x/9 < 0
x > 7 OR x < 0
Solve and graph
|x| + 7 < 16
x < 9
x > -9
