Answer:
C. Region B
Step-by-step explanation:
Since you already have the graphs of the lines, you only need to shade the proper area.
For the first equation, since y is less or equal than x-2 you have to shade the bottom part of the line.
For the second one, since y is more or equal to 1/4x+4 you have to shade the upper part of the line.
The answer is the region where the to shaded parts intersects each other.
Answer:
5/3
Step-by-step explanation:
There are a few ways to solve this problem, but here is the easiest way.
You can look at the graph and count the units.
View the attachment, and notice how the lower point goes up 5 and right 3 to get to the higher point. Remember, your slope is rise over run.
Since y changes by +5 and x changes by +3, your slope is 5/3.
Answer:
Step-by-step explanation:
The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.
Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.
Answer:
$40
Step-by-step explanation:
30 divided by 3 is 10 so 4 multiplied by 10 is $40
