Find the inverse of f(x)=(x−5)/(−4x−2)
uysha [10]

Answer:

{f}^{ - 1} (x)= \frac{  5 - 2x }{ 4x  + 1}

Step-by-step explanation:

The given rational function is

f(x) =  \frac{x - 5}{ - 4x - 2}

Let

y =  \frac{x - 5}{ - 4x - 2}

Interchange x and y

x=  \frac{y- 5}{ - 4y - 2}

Cross multiply

x( - 4y - 2)= y- 5

Expand

- 4xy   - 2x= y- 5  \\ - 4xy  - y=  2x - 5 \\y( - 4x - 1)=  2x - 5

Solve for y;

y= \frac{  2x - 5}{ - 4x - 1}

or

y= \frac{  5 - 2x }{ 4x  + 1}

Therefore

{f}^{ - 1} (x)= \frac{  5 - 2x }{ 4x  + 1}

17. The letter is J

The letter appears 3 times

18. Lefthanded students = 4 students

<h3>How to determine the factors</h3>

17. We have that 1/4 of the months of the year start with the same letter

It is important to note that:

January, June and July all start with the same letter

The letter is J

The letter appears 3 times

18. Total number of students = 24

5/ 6 are right handed

Right handed students = 24 × 5/ 6 = 4 × 5 = 20 students

Lefthanded students = 24 - righthanded students

Lefthanded students = 24 - 20

Lefthanded students = 4 students

Thus, we can see that the letter that appear in 3 months of the year is J
