Answer: should be D
I think so
Answer:
The equation is: 
Step-by-step explanation:
Given
Initial = 52000
Rate = 8000 each year
Required
Determine the equation of the graph
The equation can be determined using.

We used minus (-) because, the amount reduces as the student pays.
Let


So, we have:

Substitute values for Initial and Rate


Express as a function:

<span>Simplifying
x + 2x = 5 + 10
Combine like terms: x + 2x = 3x
3x = 5 + 10
Combine like terms: 5 + 10 = 15
3x = 15
Solving
3x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '3'.
x = 5
Simplifying
x = 5</span>
SOLUTION:
Case: Trigonometry
Method:
Let the distance between the Sun and the Earth be 'z'
The relationship between x, y and z is:

Final answer:
In sentence,
The distance between the Sun and the Earth is the product of the distance between the Earth and the moon and the cotangent of the angle x formed using the lines from the Earth and the moon.
