To simplify the expression [tex]\(-|-73|\)[/tex]:
1. Determine the absolute value: The absolute value of a number is its distance from 0 on the number line, ignoring any negative sign.
[tex]\[
|-73| = 73
\][/tex]
2. Apply the negative sign: Once we have the absolute value, we then apply the negative sign that is outside the absolute value brackets.
[tex]\[
-(-73| = -73
\][/tex]
Therefore, the simplified expression is:
[tex]\[
\boxed{-73}
\][/tex]
