When graphing inequalities, which inequality symbols have a CLOSED circle?
≤ : Less Than or Equal to
≥ : Greater than or Equal to
When you solve 2k + 10 > 30, you get the following solution:
k > 10
True
Solve.
x + 4 < 88
x < 84
Solve.
2x - 5 > 11
What is:
x > 8
x/-30 ≤ 3
x ≥ -90
In which direction would we draw the line when graphing x < -3 ? Left or right?
Left
True or False. We use an open circle to represent the inequalities < and >.
True
Solve.
z/3>7
z > 21
Solve.
9x - 1 > 71
x > 8
Solve.
5x - 16 ≥ 34
x ≥ 10

If graphing x < 5, we would put an open circle on 5 and draw a line to the right.
False. You would draw a line to the left
