If a function f(x) has an inverse f ⁻¹(x), then by definition
Differentiating both sides with respect to x yields
Now, if f(a) = b and b = f ⁻¹(a), then
5 less than the product of 5 and a number y is 22. (5y - 5 = 22)
Let's try to work backwards with this.
I
f we add 5 to 22, we get 27. (5y - 5 + 5 = 22 + 5)
27 divided by 5 is 5.4. (5y ÷ 5 = 27 ÷ 5)
Therefore,
y=5.4
Now, we can check this by plugging that into the first equation.
5y - 5 = 22
(5 × 5.4) - 5 = 22
27 - 5 = 22
22 = 22
Because both sides are equal, it proves that the answer is
y = 5.4
Answer:
How much time does it take for one book tho?
Step-by-step explanation:
If it takes two minutes for one book then it would take 1,500 minutes for all books to be labled.
2.26 x 10 to the 12 power or 2,260,000,000,000
