"...loss aversion refers to people's tendency to prefer avoiding losses to acquiring equivalent gains: it is better to not lose $5 than to find $5."
Answer:
(-2, -4)
Step-by-step explanation:
Given:
The system of equations to solve is given as:
![y=2x\\\\x+y=-6](https://tex.z-dn.net/?f=y%3D2x%5C%5C%5C%5Cx%2By%3D-6)
In order to solve this system of linear equations, we use substitution method.
In substitution method, we substitute the value of any one variable in the other equation.
So, we substitute the value of 'y' from first equation in the second equation.
This gives,
![x+2x=-6\\\\3x=-6](https://tex.z-dn.net/?f=x%2B2x%3D-6%5C%5C%5C%5C3x%3D-6)
Dividing both sides by 3, we get:
![\frac{3x}{3}=\frac{-6}{3}\\\\x=-2](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B-6%7D%7B3%7D%5C%5C%5C%5Cx%3D-2)
Now, ![y=2x=2\times -2=-4](https://tex.z-dn.net/?f=y%3D2x%3D2%5Ctimes%20-2%3D-4)
Therefore, the solution is (-2, -4)
Answer:
1312.5 cubic feet
Step-by-step explanation:
Let the swimming pool be a rectangular prism
The volume of a rectangular prism is:
Volume = length * width * depth
Length = 25 (given)
Width = 15 (given)
The depth is 4ft, but they want the volume when water is 6 inches FROM THE TOP, that is, out of 4 feet, 6 inches (1/2 feet) IS NOT FILLED. So the depth of water is
4 - 1/2 = 3.5 feet
So, we can say
Depth = 3.5 (found)
Hence, the volume would be:
Volume = 25 * 15 * 3.5 = 1312.5 cubic feet
