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!

a) 
, b) 
Step-by-step explanation:
a) The floor area of the pool is:
b) The total area of the walls of the pool is:
Answer: A. 2x2 - 3x - 8
Just subtract the functions and combine like terms
(f - g)(x) = f(x) - g(x)
(f - g)(x) = 2x^2 - 5 -(3x + 3)
(f - g)(x) = 2x^2 - 5 - 3x - 3
(f - g)(x) = 2x^2 - 3x - 8
Answer:
c is the answer
Step-by-step explanation:
when you put the negative into the second equation it makes it match up with the algebra tiles answer
GIVE ME BRAINILEST
To factor this collect the like terms..2y would go with -7y to make -5y etc. Then factor the expression by factoring out 9 Your final answer should be 9(1-y+x^2)
If you need to simplify this calculate the sum or difference between numbers (3-1+7=9)
Your final answer for this should be 9-9y+9x^2
Hope this helps!
