Question

Evaluate the expression when x = -2 and y = -4

-4x - 7y = ______

Answer 1

To evaluate the expression \(-4x - 7y\) when \(x = -2\) and \(y = -4\), we can substitute the values of \(x\) and \(y\) into the expression.

\[
-4(-2) - 7(-4)
\]

Now, calculate each term:

1. \(-4(-2) = 8\)
2. \(-7(-4) = 28\)

Now add the two results together:

\[
8 + 28 = 36
\]

So, the value of the expression when \(x = -2\) and \(y = -4\) is:

\[
\boxed{36}
\]
