Which of the following best describes interval C on the graph shown?

Slav-nsk [51]

Note: The missing graph is attached below.

Answer:

'linear decreasing' best describes interval C on the graph shown.

Step-by-step explanation:

Note: The missing graph is attached below.

From the attached graph, it is easy to figure out that the interval C on the graph shown is showing a straight line. So the graph of the function would be linear.

Also on the interval C, the value of y is decreasing as the value of x increase. So, the slope of the straight line would be negative.

So the interval C indicates that the function is decreasing there.

Therefore, 'linear decreasing' best describes interval C on the graph shown.

What is the solution to this system of linear equations? x + y = 4 x − y = 6

Amiraneli [1.4K]

X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
