Given :- 

C is the midpoint of BD .
BC = x + 7
CD = 8x

To Find :-

Value of BD ( correct )

Answer :- 

As C is the midpoint , we can say that the line is BCD . So that ,

BC + CD = BD

Substitute the values ,

( x+7 ) + 8x = BD
BD = x + 8x + 7
BD = 9x + 7 .

Hence the value of BD is 9x + 7 .

$-(6)^{-1} = ?$
Representing in fraction for the best understanding
 $-(\frac{6}{1}) ^{-1} = ?$ 
When the exponent is negative, the inversion is made, the numerator becomes the denominator, and the denominator becomes the numerator, and the change of signal from the exponent, which was negative, becomes positive.

 $-( \frac{1}{6} )^1 =$
$\boxed{\boxed{- \frac{1}{6}}}\end{array}}\qquad\quad\checkmark$
