It means the variable y is equal to the negative variable of x.
Answer:
You can cancel your investment without wasting a lot of money.
Step-by-step explanation:
Short-term means that you dont have it for a long time, so you could basically wait it out and then cancel.

4(2x - 1) + 3(2x + 5)
8x - 4 + 6x + 15
14x + 11 (the answer).
3, 1, -1, -3, -15 (the 10th term)
Let me know if you need working on this part :)
You can either use the inverse function theorem or compute the general derivative using implicit differentiation. The first method is slightly faster.
The IFT goes like this: if f(x) is invertible and f(a) = b, then finv(b) = a (where "finv" means "inverse of f").
By definition of inverse functions, we have
f(finv(x)) = finv(f(x)) = x
Differentiating both sides of the second equality with respect to x using the chain rule gives
finv'(f(x)) * f'(x) = 1
When x = a, we get
finv'(b) * f'(a) = 1
or
finv'(b) = 1/f'(a)
Now let f(x) = sin(x), which is invertible over the interval -π/2 ≤ x ≤ π/2. In the interval, we have sin(x) = √3/2 when x = π/3. We also have f'(x) = cos(x).
So we take a = π/3 and b = √3/2. Then
arcsin'(√3/2) = 1/cos(π/3) = 1/(1/2) = 2
To get the next term you multiply by 3.
The common ratio is 3.
