Mark said he can decompose five six into three fractions with three different numerators and the same denominator is this possib

Kazeer [188]

Answer:

1/6 ; 2/6 ; 2/6

Step-by-step explanation:

To split 5/6 into. 3 different fractions with the same denominator and different numerator values;

The integer value of the numerator 5 can be divided into 3 different whole Number values ;

It could be :

5 = 3 + 1 + 1

5 = 2 + 2 + 1

Hence, we could have ;

3/6 +. 1/6 + 1/6

2/6 + 2/6 + 1/3

F-20f=21 what’s the answer

Virty [35]

$\bold{[ \ Answer \ ]}$

$\boxed{\bold{F \ = \ -\frac{21}{19} }}$

$\bold{[ \ Explanation \ ]}$

$\bold{Solve: \ f \ - \ 20f \ = \ 21}$

-----------------------------------

$\bold{Add \ Similar \ Elements:f-20f=-19f}$

$\bold{-19f=21}$

$\bold{Divide \ Both \ Sides \ By \ -19}$

$\bold{\frac{-19f}{-19}=\frac{21}{-19}}$

$\bold{Simplify}$

$\bold{F \ = \ -\frac{21}{19}}$

$\boxed{\bold{[] \ Eclipsed \ []}}$

Given the function f(x) = 3 (x - 9) + 6 which of the following represents f-1 (x)?

igomit [66]

Answer:

$f^{-1}$ (x) = $\frac{1}{3}$ x + 7

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 3(x - 9) + 6 ← distribute and simplify right side

y = 3x - 27 + 6 = 3x - 21 ( add 21 to both sides )

y + 21 = 3x ( divide all terms by 3 )

$\frac{1}{3}$ y + 7 = x

Change y back into terms of x with x = $f^{-1}$ (x) , thus

$f^{-1}$ (x) = $\frac{1}{3}$ x + 7
