Given: Density of tank = 0.4 fish over feet cubed.
We know that, 
Therefore,

Hence, the volume of the tank = 
Answer:
(3,8)
Step-by-step explanation:
The point W of the pre-image is at (1, 6).
The figure went through two transformations.
The first is a reflection in the y-axis.
We just negate the coordinate of W to get;
W'(-1,6)
The next transformation is the translation by the rule.


Therefore W'' has coordinates (3,8)
Yes. It is simplified all of the way.
