Umnica [9.8K]

Answer:

$\boxed{\sf \ \ \ f^{-1}(x)=\dfrac{x+1}{5} \ \ \ }$

Step-by-step explanation:

hello

f(x)=5x-1

what can we say about $f^{-1}(x) ?$

$(fof^{-1})(x)=x=f(f^{-1}(x))=5f^{-1}(x)-1$

so

$5f^{-1}(x)-1=x\\ 5f^{-1}(x)-1+1=5f^{-1}(x)=x+1 \ \ \ add \ \ 1\\ f^{-1}(x)=\dfrac{x+1}{5} \ \ \ divide \ \ by \ \ 5$

hope this helps

No of People who can speak French is $n(F)=45$

No of People who can speak Spanish is $n(S)=42$

No of People who can speak both English and French $n\left ( E\cap F\right )=27$

No of People who can speak both English and Spanish $n\left ( E\cap S\right )=25$

No of People who can speak both French and Spanish $n\left ( F\cap S\right )=16$

No of people who can speak all languages is $n\left ( E\cap F\cap S\right )=9$

no of People who can Speak at least one Language is

$n\left ( E\cup F\cup S\right )=n\left ( E\right )+n\left ( F\right )+n\left ( S\right )-n\left ( E\cap F\right )-n\left ( E\cap S\right )-n\left ( F\cap S\right )+n\left ( E\cap F\cap S\right )$
