One number is six times as large as another. The sum of their reciprocal is 7. What are the numbers

RideAnS [48]

X=6y

sum of their reciprocals
(1/x)+(1/y)=7
x=6y
1/6y+1/y=7
1/6y+6/6y=7
7/6y=7
times both sides by 6y
7=42y
divide both sides by 42
1/6=y

x=6y
x=6(1/6)
x=6/6
x=1

the numbers are 1 and 1/6

Answer:

It is proved that $f(x)g(x)=|x|=|x-4|-4$ .

Step-by-step explanation:

Given functions are,

$f(x)=|x|$

$g9x)=|x-4|-4$

To show,

$f(x)g(x)=|x|=|x-4|-4$

Consider,

$(fg)(x)=f(g(x))=f(|x-4|-4)=||x-4|-4|$

now if,

$x>4\implies x-4>0$ then $(fg)(x)=||x-4|-4|=|x-4|-4$

$x$ then $(fg)(x)=||x-4|-4|=||-(x+4)|-4|=|x+4-4|=|x|$

Hence the reslt.
