Hello!
The equation for an exponential deprecation model like this is
, where a is the starting value, x is the number of years passed, and r is the amount the value deprecates each year.
We know what a and r are: a = 1600, as that is the original cost of the computer, and r = .18, as that's how much it decreases by. Substitute these two into the equation.
We get
. Now, subtract 1 - .18 to get our final answer.
is therefore the final model.
Hope this helps!
If you solve it into point-slop form, the equation is y = -3x + 20, then put into standard form is 3x + y = 20. That's your answer.

Answer:
<h2> TRUE</h2>
Step-by-step explanation:
3x + y = 9 and y = -4x + 10
so:
3x + (-4x + 10) = 9
3x - 4x + 10 = 9
- x = - 1
x = 1
