Answer:
B. f -1(x) = x + 2 / 5

Step-by-step explanation:
To find the inverse of a function we need to interchange x and y an solve for y.
Since
, then



Add 2 to both sides


Divide both sides by 5




We can conclude that the correct answer is B. f -1(x) = x + 2 / 5
Step-by-step explanation:
Wages
£450
450 x 1.02 = 459
Rent
£200
200 x 1.05 = 210
wages increases by £9
rent increases by £10
No the increase in her wages will not fully pay for the increase in the rent
So if you have 1 bag then you have 2kg
if you have 2 bags then you have 4kf
so the equation would be 2n=how many kg
because each bag of sugar is multiplied by 2 to get the result/answer
so 2n=answer
Answer:
A. (1 + 1/26)²⁶
Step-by-step explanation:

and e ≈ 2.71828
The greater the value of n,the closer is the value of the expression (1+ 1/n)ⁿ to the value of e.
Of the given options, the greatest value of n = 26.
Hence (1 + 1/26)²⁶ is closer to the value of e.
B because the denominators, 4 and 2, are both fators of 8
