Answer:

Inverse of the function does not exist.

Step-by-step explanation:

Inverse of a function: Inverse of a function $f(x)$ is a function that brings range to domain of $f(x)$ .

$f(x)=y\ inverse\ function\ is\ f^{-1}(y)=x$ .

Given $f(x)=|x|$

This function is not one-one map because $f(x)=f(-x)$

$f(2)=2,\ f(-2)=2 \Rightarrow f(2)=f(-2)$

Inverse function exists only if the function is one-one map.

Hence here inverse function does not exist.

In the rhombus m 1=18x m 2=x+y and m 3=30z. Find the value of x+y+z

ra1l [238]

A Rhombus has four equal straight sides. We can assume that the rhombus in this problem is square-shaped with 90° angles.

m1 = 18x ; 90 = 18x ; 90/18 = x ; 5 = x
m2 = x + y ; 90 = 5 + y ; 90 - 5 = y ; 85 = y
m3 = 30z ; 90 = 30z ; 90/30 = z ; 3 = z

x = 5 ; y = 85 ; z = 3

x + y + z ⇒ 5 + 85 + 3 = 93
