A function is positive if it lies above the x axis.
This function is positive before x = -4, i.e. over the interval ![(-\infty, -4)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-4%29)
It is negative elsewhere, i.e. over the interval ![(-4, \infty)](https://tex.z-dn.net/?f=%28-4%2C%20%5Cinfty%29)
So, the only correct option is the second one.
The container will take 25 minutes to go from full to empty.
Explanation:
In 15 minutes, the container has lost 3 gallons of water (
5
−
2
=
3
).
Since the leak is at a constant rate, we can determine that every five minutes the container loses one gallon.
So for the container to lose the full 5 gallons will take 25 minutes (
5
×

=
25
)
Answer:
-1
Step-by-step explanation:
The line goes down 1 grid square for each grid square to the right. Each grid square represents 1 unit in both the x- and y-directions. That means the slope is ...
m = rise/run = -1/1 = -1
The slope of the line is -1.
