Given f(x) = 5x + 1 divided by 2, solve for f^-1(8). O a
3
O b
7
О c
10
O d
20

Step-by-step explanation:

Given the function f(x) = (5x+1)/2

We are to find the inverse first as shown;

let y = f(x)

y = (5x+1)/2

Replace y with x

x = (5y+1)/2

Make y the subject of the formula;

2x = 5y+1

5y = 2x-1

y = (2x-1)/5

f^-1(x) = (2x-1)/5

f^-1(8) = 2(8)-1/5

f^-1(8) = 16-1/5

f^-1(8) = 15/5

f^-1(8) = 3

Hence the answer is 3

answer: jasmine will bake 4/3 or 1 1/3 cookies in an hour

step-by-step explanation:

if u add 1/3 every 15 minutes after an hour u will have 4/3 or 1 1/3

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
