Answer:
n = 7
Step-by-step explanation:
3(n - 4) = 9
3n - 12 = 9
3n = 9 + 12
3n = 21
n = 21 ÷ 3
n = 7
These angles rotate in a clockwise direction

<h2>Writing an linear equation from a given scenario</h2>
Answer:
Choice B
<h3>
Step-by-step explanation:</h3>
<em>Please refer to my answer from this question to know more about writing a </em><em>linear</em><em> </em><em>equation</em><em> from a given scenario: </em><em><u>brainly.com/question/24599307</u></em>
Scenario: A submarine dives
feet per minute.
We let
, be the position of the submarine from sea level as a function of
, the time (in minutes) since the submarine dived.
The given scenario states that for every minute, the position of the submarine <u>decreases</u> (because the submarine is going in a downward direction) by
feet. So
can be defined as
.
Now we can select two points for the graph. We can select points
and
.
Evaluation of function:


Our points are
and 
Choice A doesn't touch our chosen points. In Choice C, it would be the case if the submarine is going in upward direct.
So the correct graph is Choice B.
