Answer: W = 112 carats
Step-by-step explanation: Let W be the original weight.
So we have
W - 45 = 67 add 45 to both sides
And that equals 112 carats
The inverse of the given function is y = 3-x/3. The graph is attached below.
<h3>Inverse of a function</h3>
Functions are written in terms of variables. Given the linear function
f(x) = -3x + 3
Find the inverse
y = -3x + 3
Replace the variables
x = -3y + 3
Make y the subject of formula
3y = -x + 3
y = 3-x/3
Plot the graph of the resulting function

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)
