Place the steps for finding f -1(x) f(x)=2x+5

Mathematics

Answer:

f^{-1}(x) = \frac{x-5}{2}

Step-by-step explanation:

f(x) = 2x+5

Step 1) Replace y = f(x)

y = 2x+5

Step 2) Exchange x and y

x =2y+5

Step 3) Solve for y

x =2y+5

Subtracting both sides by -5

x - 5= 2y

2y = x-5

Dividing both sides by 2

y = \frac{x-5}{2}

Step 4) Replace y = f^{-1}(x)

f^{-1}(x) = \frac{x-5}{2}

What is the value marginal product of labor if p = $10, mpl = $25, and apl = 40? multiple choice $400 $10,000 $250 $1,000
ioda

If P=$10, MPL= $25 and APL=$ 40, then the value of marginal product of labor is $250

The marginal product of labor (MPL) is the change in output that results from employing an added unit of labor.

The average product of labor (APL) is the total product of labor divided by the number of units of labor employed.

Here,

P= $10

The marginal product of labor (MPL)= $25

The average product of labor (APL)= $40

The value of marginal product of labor= P × The marginal product of labor (MPL)

The value of marginal product of labor= 10×25=$250

Hence, If P=$10, MPL= $25 and APL=$ 40, then the value of marginal product of labor is $250

Camille uses 7.9 pints of blue paint and white paint to paint her bedroom walls. 1/4 of this amount is blue paint, and the rest
Mila [183]
First you do 7.9/ 1/4, that gets you 1.975. that is how much blue paint there is. Then you do 7.9-1.975= 5.925, which is how much white paint she used. So in total she used 1.975 pints of blue paint, and 5.925 pints of white paint.

(-12,16) and (-4,-2)find the slope
cestrela7 [59]

Answer:

It's -9/4 or -2 1/4. please mark me brainliest <3

Step-by-step explanation:

1) label x1, y1, x2, and y2.

x1     y1       x2 y2

(-12, 16)     (-4,-2)

2) Remember the formula is y2-y1

                                               --------

                                                x2-x1

3) substitute

-2-16

--------

-4-(-12)

4) two minuses (negatives) is a positive (+)

so,

-2-16             -18

---------=       --------

-4+12               8

5) simplify

-18 divided by 2          -9

-----                          =   -------    or -2 1/4

  8 divided by 2             4
