Hello!

The equation for an exponential deprecation model like this is y = a(1-r)^{x}, 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 y = 1600(1-.18)^{x}. Now, subtract 1 - .18 to get our final answer.

y = 1600(.82)^{x} is therefore the final model.

Hope this helps!

Solve for y , what is 9x+3y=4 ??
lora16 [44]
To solve for y, isolate the variable to one side.
 9x+3y=4
-9x      -9x
~~~~~~~~
3y= -9x+4
~~~~~~~~
3y= -9x+4 (Divide both sides by 3)

y=-3x+4

Two dice are rolled. Define the events as follows: A : sum of 7, B : doubles, C : sum of 8
love history [14]

Answer: for a sum of 7 would either be 6 and 1, 5 and 2 or 4 and 3. you can roll a double 1,2,3,4,5,6. the sum of 8 would be 2 and 6, 3 and 5 and a double 4,

Step-by-step explanation:

well the there are six sides on a die so 6 x 2 is 12 so the max sum you can get is 12. So you take 7 and you start adding up to 7, same thing for sum of 8. since there is 6 sides and a pair of dices you will roll six doubles
