For this case we must find the inverse of the following function:
We follow the steps below:
Replace f(x) with y:
We exchange the variables:
We solve for "y":
Multiply by -2 on both sides of the equation:
We raise both sides of the equation to the square to eliminate the radical:
We subtract 3 from both sides of the equation:
We change y by f ^ {- 1} (x):
Answer:
Answer:
C(t) = $28,000(0.811)^t (Answer A)
Step-by-step explanation:
The value of the car is decreasing. Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.
Please use " ^ " to indicate exponentiation.
Then the desired formula is C(t) = $28,000(0.811)^t (Answer A)

Answer: 20 grams
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The amount of grams of silver he lost at the Holdong mine heist(x) plus 5 , is equal to the amount of grams of silver he lost in the Hysean mine heist. (25)
Mathematically speaking:
x+5=25
Solving for x
x = 25-5
x = 20 grams
Feel free to ask for more if needed or if you did not understand something.
Step-by-step explanation:
Rearrange this algebraically to solve for
Price per pound
. To do this, divide both sides of the equation by
Number of pounds
to get
Price per pound
by itself.
Total cost = number of pound
=Total of cost /Number of pounds
=33/5
=$6.6
