set f(x) equal to y

y = 19/ x^3

swap x and y

x = 19/y^3

make y the subject

xy^3 = 19

y^3 = 19/x

y =  \sqrt[3]{ \frac{19}{x} }

then just replace y with f^-1(x)

f(x) =  \sqrt[3]{ \frac{19}{x} }

hope this helped! have a good day ~ •lipika•

<h2>Answer:</h2>

The inverse of the function F(x) is:

          \sqrt[3]{\dfrac{19}{x}}

<h2>Step-by-step explanation:</h2>

We are given a rational function F(x) as:

F(x)=\dfrac{19}{x^3}

The steps to find the inverse function of a given function f(x) are as follows:

1.   Put f(x)=y

2.  Interchange the value of x and y

3.  Solve for y.

Hence, we find the inverse of F(x) as follows:

F(x)=y

i.e.

\dfrac{19}{x^3}=y

Now we interchange x and y

i.e.

\dfrac{19}{y^3}=x

Now we solve for y as follows:

y^3=\dfrac{19}{x}\\\\i.e.\\\\y=\sqrt[3]{\dfrac{19}{x}}

      Hence, the inverse function is:

                 \sqrt[3]{\dfrac{19}{x}}

Here is your answer

B. (12,30)

REASON:

Given,

y= 2x+6 .......(i)

3x-y= 6 .......(ii)

Putting the value of y from eq.i in eq.ii we get

3x-(2x+6)=6

3x-2x-6=6

=6+6

x=12

Putting x=12 in eq.i we get

y= 2x+6

y= 2×12+6

y= 24+6

y= 30

So,

\bold{x=12 and y= 30}

Hence answer is (12,30) in which x=12 and y=30

Answer:

? = 13

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

?² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )

? = \sqrt{169} = 13

It's a system of equations x=-4y x+6y=18
Misha Larkins [42]
Subsitute -4y for x

-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back

x=-4y
x=-4(9)
x=-36

(x,y)
(9,-36)

Convert 5280 vodas to pivos. Show three significant figures for your answer.
Finger [1]

(5280 vodas) * (1/2.71828 moloko/voda) * (1/3.1416 pivo/moloko) ≈ 618 pivos

(because 5280 has 3 significant digits)
