Solve each inequality. State the solution set in interval notation and sketch its graph.
6 <12 - r
Solve each inequality. State the solution set in interval notation and sketch its graph.
6 <12 - r
Subtract 12 from both sides to get:
-6 < -r
-------
When you multiply both sides by -1 you get 6 > r
You can write this as r < 6
Interval notation: (-inf,6)
