Answer:
The solution set to the absolute value is:
or 
Negative real numbers are not included in the solution set, as for 
, 
.
Step-by-step explanation:
From Mathematics, we know that absolute values are defined by the following characteristics:
1) For 
, 
2) For ,
Then, if , then the solution set to the absolute value is:
or
Negative real numbers are not included in the solution set, as for , .
Answer:
(4, - 2 )
Step-by-step explanation:
Given the 2 equations
x = 4 → (1)
- y = 
x → (2)
Substitute x = 4 into (2)
- y = × 4 = 2 ( multiply both sides by - 1 )
y = - 2
Solution = (4, - 2 )
Answer:
The third graph.
Step-by-step explanation:
The equations for the lines will be
P(x) = 2x-4
l(x) = -2x-4
When x = 0 both of these functions equal -4. The only graph where this happens is the third one.
You can check this by looking at the slopes and plugging in points.
