If f(x) and f–1(x) are inverse functions of each other and f(x)=2x+5, what is f–1(8)?
yarga [219]

f(x)=2x+5

first find inverse

write it without f(x)

y = 2x +  5

x = 2y + 5  swap the variables, now solve for y

-  5      -5

x - 5 = 2y

/2         /2  divide both sides by 2

(x-5)/2 = y


so f-1(x) = (x-5)/2

f-1(8) = (8-5)/2

         = (3)/2

f-1(8) = 3/2

How to calculate the critical value of z distribution ?
pshichka [43]

Answer:

Compute alpha (α): α = 1 - (confidence level / 100)

Find the critical probability (p*): p* = 1 - α/2

To express the critical value as a z-score, find the z-score having a cumulative probability equal to the critical probability (p*).

Diego is solving this system of equations:
USPshnik [31]

The solutions of the equations are x = 1 and y = 2

The system of equations are

4x + 3y = 10

-4x + 5y = 6

Here we have to use the elimination method. Eliminate the x term and find the value of y term

Add both equation

3y + 5y = 10 +6

Add the like terms

8y = 16

y = 16 / 8

Divide  the terms

y = 2

Substitute the value of x in the first equation

4x + 3y = 10

4x + 3×2 =  10

Multiply the terms

4x + 6  = 10

4x = 10 - 6

4x = 4

x = 4 / 4

Divide the terms

x = 1

Hence, the solutions of the equations are x = 1 and y = 2
