The inverse, f-1(x), of f(x) =
X + 5
Х
5
can be written as
X- 1

A) f(2) = 7/2

B) f'(2) = 5

Step-by-step explanation:

We are given that;

f(x) = (x + 5)/x

f'(x) = 5/(x - 1)

A) Now, f(2) will be gotten by Plugging in 2 for x in to f(x) equation;

f(2) = (2 + 5)/2

f(2) = 7/2

B) similarly, f'(2) will be gotten by Plugging in 2 for x in f'(x) equation. Thus;

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

f'(2) = 5/1

f'(2) = 5

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
