Answer:
- 2 < x < 2
Step-by-step explanation:
Given
- 3 < 2x + 1 < 5 ( subtract 1 from each interval )
- 4 < 2x < 4 ( divide each interval by 2 )
- 2 < x < 2
Answer:
Undefined
Step-by-step explanation:
subtract x from both sides
Answer:
NO SOLUTIONS
Step-by-step explanation:
x+6=x
-x -x
6=0
6 does not equal to zero

Answer:
Step-by-step explanation:
According to the graph, the system is formed by two inequalities. Let's find out the equation to each line in first place.
Notice that the upper line passes through points (-1,0) and (0,1). First, we find its slope
Then, we use the point-slope formula to find the equation
Now, the dashed line indiactes that the inequalities must have sings < or >.
Notice that point (0,0) is part of its solution, that means the inequality is
We do the same process to find the other inequality.
The line passes through points (0,-2) and (2,0).
Then,
Notice that point (0,0) is part of its solution, so the inequality is
Therefore, the system of inequalities is
Answer:
y<x+1 y>x-2
Step-by-step explanation:
upper line: (0,1) (-1,0)
y=x+1
Lower line: (0,-2) (2,0)
y=x-2
I did not see any solid boundry on the line
Shaded: y<x+1 y>x-2
