Which function is the inverse of f Superscript negative 1 Baseline (x) = negative one-fifth x minus four-fifths?
DedPeter [7]

Answer:

f(x) = -5x - 4

Step-by-step explanation:

We want to get the inverse of the following function:

f^-1(x) = (-1/5)x - 4/5

To do that, we have to replace x with f(x) and f^-1(x) with x, as follows:

x = (-1/5)f(x) - 4/5

And then solve for f(x), the inverse of f^-1(x).

x + 4/5 = (-1/5)f(x)

f(x) = -5x + (-5)4/5

f(x) = -5x - 4

To check our result we compute a pair (x, f(x))

x   f(x)

1   -5*1 - 4 = -9

which has to be equivalent to (-9, 1) in the original function

x      f^-1(x)

-9     (-1/5)*(-9) - 4/5 = 1

Serga [27]

Answer:

A


Step-by-step explanation:


To convert mixed number as improper fractions, use this rule:

A\frac{B}C}=\frac{(A*C)+B}{C}


<u>For Juan:</u>  (4\frac{1}{6})

4\frac{1}{6}=\frac{(4*6)+1}{6}=\frac{25}{6}


<u>For Antonio:</u>  (3\frac{2}{3})

3\frac{2}{3}=\frac{(3*3)+2}{3}=\frac{11}{3}


Answer choice A is correct.

A drawer of loose socks contains 2 red socks, 2 green socks, and 6 white socks. Which best describes how to determine the probab
kenny6666 [7]
Well, before you draw out the first sock, you had 60% chance of getting a white sock since six of the ten socks are white! (6/10)

So, if you were to not replace the first drawn white sock, your percentage goes to 55.5556%! This is because you now have 5/9 socks remaining in the drawer being white!
