100
When graphing inequalities, which symbols have a CLOSED circle?
< Less Than
> Greater Than
100
Is the statement true
2x > -6
x = -3
False
100
Solving Inequalities
Solve for x.
2x > 8
What is:
x > 4
100
3x+4>10
x>2
100
Will we need to flip the sign at ANY point?
3x > 24
NO
200
When graphing inequalities, which inequality symbols have a FILLED IN circle?
≤ : Less Than or Equal to
≥ : Greater than or Equal to
200
Is the statement true?
2k + 30 > -10
k > -20
True
200
Solve the Inequality
x + 4 < -88
What is:
x < -92
200
6z + 2 ≥ 20
z ≥ 3
200
Will we need to flip the sign at ANY point?
-4x < 16
YES (We will divide by NEGATIVE 4)
300
Which direction do we shade for x < -3 ?
What is
Left
300
We use an unfilled circle to represent the inequalities < and > ?
True
300
Solve the Inequality
z/30>70
z > 2,100
300
2/3y - 5 ≤ 7
y ≤ 18
300
Will we need to flip the sign at ANY point?
-5x = 20
NO (this is an EQUATION, silly billy!)
400
Is the following inequality graphed correctly?
x < 6
No, the graph shows x > -6
400
If graphing x < 5, we would put an unfilled circle on 5 and shade to the right.
False.
400
Solve the Inequality
4x < -14
NOTE: The answer is NOT an integer.
x<7/2
or
x<-3.5
400
-3a + 3 < 9
a > -2
400
Will we need to flip the sign at ANY point?
x/3 = -12
NO (we will MULTIPLY by POSITIVE 3)
500
What are these symbols called:
< , ≤ , > , ≥?
(The answers are not less then, greater then, etc.)
What is
Inequalities
500
-2 is less than -10
False
500
Solve the Equation:
f - 9 < -58
What is:
f < -49
500
FIRST PERSON TO CREATE AN INEQUALITY WITH AN ANSWER OF:
X > -3
WINS!!!
Possible answers (there are infinite):
2x > -6
-4x < 12
500
Will we need to flip the sign at ANY point?
2 > 2x
YES (Our variable is not in front, so the WHOLE inequality will flip.... x < 1)
