Question

Evaluate the expression for x = –3, y = –6, and z = –9.

xz − y =

Answer 1

To evaluate the expression \( xz - y \) for \( x = -3 \), \( y = -6 \), and \( z = -9 \), we substitute the values into the expression:

1. Calculate \( xz \):
\[
xz = (-3)(-9) = 27
\]

2. Now substitute this value into the expression:
\[
xz - y = 27 - (-6)
\]

3. Simplify the expression:
\[
27 - (-6) = 27 + 6 = 33
\]

Therefore, the result of the expression \( xz - y \) is \( \boxed{33} \).
