Look at the graph at which x=3, then look and see what value y is and that will give you f(3).

Answer:

For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.

The inverse function of the given function is \mathbf{= \dfrac{28+7x}{x-1}}

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

A function g is the inverse of a function f, if and only if the values of y= f(x), x = g(y).

From the formula given:

\mathbf{y=f(x) = \dfrac{x+28}{x-7}}

Let's substitute x with y;

\mathbf{y= \dfrac{x+28}{x-7}}

\mathbf{x=\dfrac{y+28}{y-7}}

Solve for y;

\mathbf{= \dfrac{28+7x}{x-1}}

Karina ate 1/2 of the muffins. Ulysses ate 1/4 of the muffins. Zawanna ate 1/5 of the muffins. Juan ate the rest of the muffins.
erastovalidia [21]

Answer:

1/20

Step-by-step explanation:

Karina ate 1/2 of the muffins. Ulysses ate 1/4 of the muffins. Zawanna ate 1/5 of the muffins. Juan ate the rest of the muffins. What fraction of the muffins did Juan eat?

Let the total number of muffins = 1

Hence:

The fraction of muffins Juan ate =

1 - (1/2 + 1/4 + 1/5)

Lowest common denominator is 20

1 - ( 10 + 5 + 4/20)

1 - 19/20

= 1/20

The Fraction of muffins Juan ate is 1/20

HELP PLEASE ILL GIVE THE BRAINLIEST TO WHOEVER ANSWERS CORRECTLY!!!
drek231 [11]

Answer:

D. translation, yes

Step-by-step explanation:

A is out because the shapes are congruent, and if the figure was reflected, it would have been closer to the y-axis. It is the same with B, if the figure was dilated, the second figure would have been similar but not congruent. C is out because the figure is still facing the same direction.
