5/9 - 1/3•1/6 <br> Show work
gavmur [86]
- First multiply 1/3 times 1/6  across giving you 1/18

-then get the LCD of 5/9 and 1/18 which is 18
 multiply 5/9 times 2/2 to get 10/18.

-Now you can subtract
  10/18- 1/18 = 9/18

-further simplify by diving the top and bottom of 9/18 by 9
 the answer would be =1/2

<em>*Note: you do not need to get the LCD of a fraction when multiplying or dividing. You DO need the LCD when adding or subtracting a fraction.</em>

If f(x)=5x-12, find a value for $x$ so that f^{-1}(x)=f(x+1).
Vinil7 [7]

Answer:

\boxed{\sf \ \ \  x=\dfrac{47}{24} \ \ \ }

Step-by-step explanation:

Hello,

f(x)=5x-12

we need to find x so that

f^{-1}(x)=f(x+1)

<u>so first of all we can write</u>

x = (fof^{-1})(x)=f(f^{-1}(x))=5f^{-1}(x)-12\\\\5f^{-1}(x)=x+12\\\\f^{-1}(x)=\dfrac{x+12}{5}

and f(x+1) = 5(x+1) - 12 = 5x + 5 -12 = 5x - 7

then solving

f^{-1}(x)=f(x+1)

is equivalent to

\dfrac{x+12}{5}=5x-7 \ multiply \ by \ 5 \\\\ x+12 = 5(5x-7)=25x-35\\ 25x-x=12+35\\\\24x=47\\\\x=\dfrac{47}{24}

Hope this helps
