Question

2x+(-6) • (y+1) forx= -1.5 and y=-3

Answer 1

To evaluate the expression \( 2x + (-6) \cdot (y + 1) \) for \( x = -1.5 \) and \( y = -3 \), we first substitute the values of \( x \) and \( y \) into the expression.

1. Substitute \( x = -1.5 \) and \( y = -3 \) into the expression:
\[
2(-1.5) + (-6) \cdot (-3 + 1)
\]

2. Calculate \( 2(-1.5) \):
\[
2(-1.5) = -3
\]

3. Simplify \( y + 1 \):
\[
-3 + 1 = -2
\]

4. Now calculate \( (-6) \cdot (-2) \):
\[
(-6) \cdot (-2) = 12
\]

5. Now add the two results together:
\[
-3 + 12 = 9
\]

So, the value of the expression \( 2x + (-6) \cdot (y + 1) \) for \( x = -1.5 \) and \( y = -3 \) is \( \boxed{9} \).
