Final answer:
To evaluate the expression, substitute the given values and simplify.
Step-by-step explanation:
To evaluate the expression -x² + 6z / y when x = 10, y = -2, and z = -5, we substitute the given values into the expression.
Substituting the values, we get:
-10² + 6(-5) / (-2)
Simplifying further, we get:
-100 - 30 / -2
-130 / -2
65
Therefore, the value of the expression is 65.
