Which pair of functions are inverses of each other?
klio [65]

f(x) = 10x -5 and g(x) = (x+5)/10  are inverses of each other , Option D is the correct answer.

<h3>What is a Function ?</h3>

A function is a mathematical statement which relates two variables , a dependent and an independent variable.

The inverse of a function is found by replacing every y by x and vice versa , and then solve for y

The equation

f(x) = 4/x - 3

or

y= 4/x -3

Replacing y by x

x = 4/y -3

x +3 = 4/y

y = 4/(x+3)

Which do not correlate with the given inverse

f(x) = 10x -5

y = 10x -5

for finding inverse

10y -5 = x

10y = x+5

y = (x+5)/10

g(x) = (x+5)/10

Therefore , Option D is the correct answer.

The apartment building where hannah lives was built with 213,854 bricks. 
kykrilka [37]
So what this effectively means is 213854/100000
This gives 2.13854, or 2 with a remainder of 13854.

As you need complete groups the answer is 2, as the remaining 13854 cannot be used to make another group of 100000.

Divide 20 for 5 times with odd number​
sattari [20]

Answer:

No, we can't make 20 by adding 5 odd numbers.

Step-by-step explanation:

An odd number is represented by 2n+1, the sum which we got is represented in this form, so it's obviously an odd number. But 20 is an even number, so sum can't be 20.
