The equivalent expression is
\(-(3)/(5x^6y^(12))\), leading to option D as the correct choice.

To simplify the expression
\(-(9x^(-1)y^(-9))/(-15x^(5)y^(-3))\), we can use the rules of exponents and fraction simplification.

1. Combine the Numerators and Denominators:


\[ -(9x^(-1)y^(-9))/(-15x^(5)y^(-3)) = (9x^(-1)y^(-9))/(15x^(5)y^(-3)) \]

2. Combine Like Terms:


\[ = -(3)/(5) \cdot (x^(-1-5))/(y^(9-(-3))) = -(3)/(5) \cdot (1)/(x^6y^(12)) \]

3. Simplify the Fraction:


\[ = -(3)/(5x^6y^(12)) \]

Therefore, the expression is equivalent to
\(-(3)/(5x^6y^(12))\), which corresponds to option D.
