When graphing inequalities, which symbols have an OPEN circle?
< Less Than
> Greater Than
Is the statement true
2x > -6
x = -3
False. -3 would make this equal to.
Solving Inequalities
Solve for x.
2x>8
x>4
Solve for x.
x+3<-7
x<-10
Select all the values that make the following inequality true? Can have multiple answers.
x/2<=2
0, 1, 2, 3, 4, 5, 6, 7, 8 ,9
0, 1, 2, 3, 4
When graphing inequalities, which inequality symbols have a CLOSED circle?
≤ : Less Than or Equal to
≥ : Greater than or Equal to
Is the statement true?
2k + 30 > -10
k > -20
False. -20 makes it equal to.
Solve the Inequality
x+4<-88
x<-92
Solve for x.
3/4x - 5<=1
x <=8
Select all the values that make the following inequality true? Can have multiple answers.
-r<=7
-12, -8, -7.1, -6.9, -2, 0, 6.9, 7.1, 8
-6.9, -2, 0, 6.9, 7.1, 8
Which direction do we shade for x < -3 ?
Left
We use an open circle to represent the inequalities < and > ?
True
Solve the Inequality
z/30>70
z>2,100
Solve for x.
6.25x-4.25>=20.75
x>=4
Select all the values that make the following inequality true? Can have multiple answers.
-2d>=-48
-24, -20, -15, 0, 15, 24, 32, 48, 96
-24, -20, -15, 0, 15, 24
Is the following inequality graphed correctly?
x < 6
No, the graph shows x > -6
If graphing x < 5, we would put an open circle on 5 and shade to the right.
False. Shade to the left
Solve the Inequality
4x < -14
x<7/2
or
x<-3.5
Solve and graph this inequality.
3.0-2.4-x+5.6>=43.4
x<=-37.2
open circle going to the left
Select all the values that make the following inequality true? Can have multiple answers.

-27, -22, -20, -18, -17, -16, -14, -12, -7
-16, -14, -12, -7
Draw and identify each of the inequality symbols.
<, >, <=, >=, Ø
Less than, greater than, less than or equal to, greater than or equal to, and no solution
-3(2x-9) +3 <=-1
x<=5
False
Solve the Inequality:
