Inverse fraction of f(x)=2x+1

Mathematics
1 answer:
Akimi4 [234]2 years ago
6 0

Answer:

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

Step-by-step explanation:

let f(x) = y, then y = 2x + 1

rearrange, making x the subject

subtract 1 from both sides

y - 1 = 2x ( divide both sides by 2 )

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

change y back into terms of x

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

The length of a rectangle is 7 1/2 inches and the width is 4 3/4 inches. What is the ratio, using whole numbers, of the length t
Mariana [72]
Ratio is a division in its simplest form. 
To get the ratio of length to width, divide the two then simplify.

In this case, convert the length and width into decimals.

length = 7 1/2 = 7.5
width 4 3/4 = 4.75

ratio of length to width is;
7.5/4.75 = 750/475

This can now be written as; 
750 : 475
Dividing both sides by 25;

= 750/25: 475/25

= 30 : 19
