**DOUBLE JEOPARDY**
What is:
x < -4
Solve the inequality for "x".

*DOUBLE JEOPARDY*
What is
Left
"Above" the average temperature would be represented by the inequality ">"
True
Solve the inequality for "z".

What is:
x > -8
Solve the inequality for "n".
12( n + 9) < 132
n < 2
Is the following inequality graphed correctly?
x < 6
No, the graph shows
"x is greater than or equal to negative 6"
If graphing 5>x, we would put an open circle on 5 with an arrow pointing to the right.
**DOUBLE JEOPARDY**
False.
Solve the inequality for "x". CUIDADO!
x/-4 < 24
(x divided by -4)
What is:
x > -96
Solve the inequality for "v".
v/3 + 14 < 30
(v divided by 3)
v < 48
Solve the inequality for "d". CUIDADO!
8 + 4d + 12 > 32
d > 3

What is:
f < -49
Solve the inequality for "x".
CUIDADO! CUIDADO!
11 < 2 - 3x
x < -3
Would it be accurate to say that the graph of
this compound inequality solution: 6 > x > -4
is between, but does not include -4 and 6?
**DOUBLE JEOPARDY**
Yes
