Answer:
See below.
Step-by-step explanation:
The last step is incorrect. When we divide both sides by a negative the inequality is flipped. The answer is x < -1/2.
Also they omitted the other possibility that the expression in the vertical lines could be negative.
We also have the inequality
- 4x + 1 < - 3
-4x < -4
x > 1.
If an items weight is 0 it would be like a peice of paper or cotten ball. when a cotten ball is weighed it does not affect anything. as when a peice of paper is wieghed it moves its meater 1 inch.
A² + b² = c²
5² + 8² = x²
x² = 25 + 64
x² = 89
x = √89
x = 9.43
