Hi.

To formally answer your question:

D. y = 0.75<em>x</em> + 11

We can prove this by substituting <em>x</em> with 1 (the initial measurement)

y = 0.75(1) + 11 = 11.75

WHAT IS THE ANSWER??? HELP
antoniya [11.8K]

Answer:

C

Step-by-step explanation:

The graph has a  x - axis of amount of scarves in intervals of 1 and a y - axis of hours in intervals of 20

Using this information we can see that in the ordered pair, 1 represents x and 16 represents y, which means that the scarves ar 1 and the hours are 16 in the ordered pair

C makes the most logical sense because there is nothing about centimeters in the graph and the scarves are not in the y, but rather in the x

Switch the variable x and y with each other. Then the correct option is B.

<h3>What is inverse of a function?</h3>

Let the function will be

f: X → Y

Then the inverse function will be

f⁻¹: Y → X

The function is given below.

f(x) = 3x – 10

Then the inverse function of the f(x) will be

Put y in place of f(x).

    x = 3y – 10

  3y = x + 10

    y = (x + 10) / 3

Switch the variable x and y with each other.

Then the correct option is B.
