Absolute Value
With every single variable absolute value equation there will either be two solutions OR ...
No Solution
Explain when a closed circle is used in graphing an inequality.
When the number is included, less than or equal to OR greater than or equal to
Solve
2x+ 5 = 15
x=5
Solve for x
y= mx + b
y-b/m =x
What is the square root of 144?
12
|3x +5| = -10
No Solution
Explain when an open circle is used when graphing an inequality.
When the number is excluded, just greater than or less than.
23 - 4v = -7 -14v
v= -3
d= rt
Solve for t
d/r=t
How many expectations are there in this class?

|10 + 4r| = 42
-13 and 8
Explain why it is a good idea to put the variable on the left before graphing an inequlity.
Variable on the left then the inequlity sign will point the way.
6/v=8/6
4.5 or 4 1/2
P = 2L + 2W
Solve for W
P/2 - L =W
7(2x +31 -3z)
14x +217 -21z
|3x + 5x -20x +10| =2
x= 1 and 2/3 or .6666
When solving inequalities what needs to happen when you multiply or divide by a negative number ?
Must flip the inequality sign
4(1 + 7x ) =33 -x
x=1
r=stuv
Solve for u
r/stv=u

|3x2 +1|=28
x= 3 and -3
Explain the logic behnind graphing inequalities but not single variable equations.
Number of solutions for inequalities versus x=3
3x2 =27
x=3
Why are they called literal equations ?
BC there is no numeric solution because of two many variables OR any reasonable anser
