Answer: <u>C. 20-.40p</u>

Step-by-step explanation:

We know that from the given information that each pound is worth 40 cents, and that its being subtracted from the twenty dollar bill.  

"Why are the others choices wrong?"

A. p-20, isn't the proper equation due to the stated information.

B. B. 20 -40p, this equation has Zelma pay $40 dollars each pound, which isn't correct due to what the text has stated ("for 40 cents per pound").

D. 40p-20, from the given text, this equation is wrong ("She pays the clerk with a twenty-dollar bill), it never states that she will be charged twenty dollars, or be given forty for each pound.

Given f(x) = 4x + 2, find f-1(3).
Alexxandr [17]

Answer:

  1/4

Step-by-step explanation:

The inverse function tells you the input value that corresponds to the given output value of the function.

<h3>Application</h3>

You want f^-1(3), which is the value of x such that f(x) = 3.

  f(x) = 3 = 4x +2

  1 = 4x . . . . . . subtract 2

  1/4 = x . . . . . divide by 4

The inverse function of 3 is 1/4:

  \boxed{f^{-1}(3)=\dfrac{1}{4}}
