Please help me with this question please help me I beg you
Sindrei [870]

Step-by-step explanation:

Given

f(x) = 5 / 2x - 1

f^-1( x) = ?

Let

y = f(x)

y = 5/2x - 1

Interchanging the roles of x and y we get

x = 5/2y - 1

2y - 1 = 5/x

2y = 5/x - 1

y = (5/x - 1)/ 2

f^-1(x) = ( 5/x - 1) / 2

Hope it will help :)

Can someone helpp with thissssssssssssssss
Law Incorporation [45]

Answer:

Step-by-step explanation:

let’s say each side length is called a, b, and c

to find out if a side length is a solution you have to know that

a < b + c

b < a + c

c < a + b

if all of these are true then the given lengths can be the sides of a triangle

ex:

a = 3, b = 4, c = 5

3 < 4+5

3 < 9

this is true

4 < 3+5

4 < 8

this is true

5 < 3+4

5 < 7

this is true

so these side lengths can make a triangle

however, if one of these inequalities weren’t true (ex: 9 < 4) you wouldn’t be able to make a triangle with the given side lengths
