Equations
Solve for x:
9x+2 = x+4
x= 4
Would I use an open or closed circle to graph this inequality?
5x + 3 > 13
Open Circle
How many solutions does an equation that is reduced to 5x+3 = 5x +3 have?
Infinite.
Solve for x:
4x+3 = 2x-9
x= -6
Would I use an open or closed circle to graph this inequality?
5x + 8 ≥ 13
Closed Circle
How many solutions does an equation that is reduced to 6x+3 = 6x-3 have?
Zero Solutions
Solve for x:
-4x + 5 -2x = 10 - x
-1 = x
What direction would I shade a graph for this inequality?
x > 4
Right
How many solutions does an equation that is reduced to x+2 = 3x +3 have?
one solution
1/2 (10x-4) = 1/3(9x-3)
x = 1/2
What direction would I shade for this inequality?
x < -3
Left
3(2x+1) = 6x+3
Infinite
2/6x + 1/3x = 4
x=6
What direction would I shade for this inequality?
(hint you need to solve first)
-2x > 10
Left
4x+8 = 2(3x+2)
