Need explanation 20 points<br> The function f is such that f(x) = 2x - 6<br> Find f^-1(x)

Dvinal [7]

HEYA! <3

Explanation :

<u>GIVEN </u> :

f(x) = 2x - 6

<u>TO </u><u>FIND</u><u> </u> :

Inverse of f(x) i.e $f ^{ - 1} (x)$

<u>S</u><u>OLUTION </u> :

FOLLOW THESE THREE STEPS :

LET Y = f(x)

$\longrightarrow \tt{y = 2x - 6}$

$\longrightarrow{ \tt{ \: 2x - 6 = y}}$

MAKE X A SINGLE TERM IN LHS SIDE

$\longrightarrow{ \tt{2x = y + 6}}$

$\longrightarrow{ \tt{x = \frac{y + 6}{2} }}$

INTERCHANGE THE VALUE OF X AND Y

$\longrightarrow{ \tt{y = \frac{x + 6}{2} }}$

Hence ,

$\boxed{ \boxed{ {f}^{ - 1} (x) = \sf{ \bold{ \frac{x + 6}{2} }}}}$

Hope I helped!

Have a wonderful day / night !

A market analyst has projected that the cost of producing d dog leashes will be given by the polynomial 9000 + 3.2d. The revenue

Sholpan [36]

Answer:

C. $-0.00005d^2+11.8d-9000$

Step-by-step explanation:

Given:

Cost Price for producing 'd' dog lashes = $9000+3.2d$

Revenue Generated from selling 'd' dog lashes = $d(15-0.00005d)$

We need to find the profit earned from producing and selling 'd' dog lashes.

Solution:

Now we know that;

profit earned from producing and selling 'd' dog lashes can be calculated by Subtracting Cost Price for producing 'd' dog lashes from Revenue Generated from selling 'd' dog lashes.

framing in equation form we get;

Profit earned = $d(15-0.00005d)-(9000+3.2d)$

Now Applying Distributive property we get;

Profit earned = $15d-0.00005d^2-9000-3.2d$

Now Combining like terms we get;

Profit earned = $-0.00005d^2+15d-3.2d-9000$

Profit earned = $-0.00005d^2+11.8d-9000$

Hence Profit earned from producing and selling 'd' dog lashes is $-0.00005d^2+11.8d-9000$ .

The sum of 13 divided by a number and that number divided by 13

7nadin3 [17]

Sum means add

the number is x

13 divided by a number is 13/x
the number divided by the number is x/13

so
$\frac{13}{x}+\frac{x}{13}$
also can be simplified to
$\frac{169}{13x}+\frac{x^2}{13x}$ or
$\frac{x62+169}{13x}$

translated it is $\frac{13}{x}+\frac{x}{13}$ where x is the number
