Solve and graph the inequality: 3x - 7 > 5.
Start by adding 7 to both sides.
Graph the inequality: x ≤ 2.
Remember, ≤ means 2 is included.
What should you do when multiplying both sides of an inequality by a negative number?
Think about how the direction of the inequality changes.
True or False: The solution set of an inequality can include infinity.
Consider the nature of inequalities.
If 4x - 5 < 7, how do you solve for x and represent this graphically?
Start by adding 5 to both sides.
In the system x + y ≥ 10 and x < 2, what can we determine about the solution region?
Consider the lines that establish the boundaries of the inequalities.
