Answer:
(4,0) and (- 2,0): Answer
Step-by-step explanation:
Absolute value questions have two essential steps.
1. Solve the equation as it is written.
2. Solve it changing the sign of the right hand side. I will include a graph to confirm my answer
4*abs(x - 1) = 12 Divide by 4
- abs(x - 1) = 12/4
- abs(x - 1) = 3 Equate this to 3
- x - 1 = 3 Add 1 to both sides
- x - 1 + 1 = 3 + 1 Combine
- x = 4
4*abs(x - 1) = - 12 Divide by 4
- abs(x - 1) = - 12/4
- abs(x - 1) = - 3
- x - 1 = - 3 Add 1 to both sides
- x - 1 + 1 = -3 + 1
- x = - 2
So this has 2 answers

Answer:
Productivity fell by about 16.7%.
Step-by-step explanation:
Consider the provided information.
Dilbert’s Incorporated produced 6,000,000 units of software in 2005.
In 2006 production was 7,000,000 units.
In 2005 they was making 6,000,000 units in 10,000 hours.
Per hour output =
In 2005 per hour output was 600.
In 2006 they are making 7,000,000 units in 14,000 hours
Per hour output =
In 2005 per hour output is 500.
That means the per hour output decreases. Or we can say that the productivity falls.
The difference between the production:
7,000,000-6,000,000=1,000,000
Therefore, they increase 1,000,000 units.
Decrease in productivity =
Hence, productivity fell by about 16.7%.
