Answer:

f^-1(x) = 4x - 40

Step-by-step explanation:

let y = f(x)

y = 1/4x + 10

4y = x + 40

x = 4y - 40

f^-1(x) = 4x - 40

Three rational numbers between 1/3 and 1/5
Gala2k [10]

Three rational numbers between

1/3 and 1/5 are 4/15, 3/10, and 7/30

Given:The two numbers are 1/3 and 1/5

To find:The rational number between two numbers

Solution:Now, to find the rational number, add the numbers and divide their sum by 2.

(i) First rational number between

1/3, 1/5 = 1/3+1/5=8/5

Divide 18/5 by 2------> 8/15 x 1/2= 8/30= 4/15

The series becomes, 1/3, 4/15, 1/5

(ii) Second rational number

= 4/15+1/5 = 7/15

Divide

7/15 by 2 ------> 7/15 x 1/2 = 7/30

Hope this helps!

Please help with the 2 questions ive attached, i dont understand it at all
vesna_86 [32]

Answer:

see explanation

Step-by-step explanation:

(a)

Consider the denominator

To obtain 5xy from x , multiply by 5y

Thus numerator is multiplied by 5y, that is

\frac{1}{x} = \frac{5y}{5xy}

(b)

Consider the numerator

To obtain 5ab² from ab, multiply by 5b

Thus denominator is multiplied by 5b, that is

\frac{ab}{2c} = \frac{5ab^2}{10bc}
