Question

Evaluate the expression for t = 1 and u = 5. Simplify your answer.

–10
tu + u
=

Answer 1

To evaluate the expression \(-10 / (tu + u)\) for \(t = 1\) and \(u = 5\), we first substitute the values of \(t\) and \(u\) into the expression.

1. Substitute \(t = 1\) and \(u = 5\):
\[
tu + u = (1)(5) + 5
\]

2. Calculate \(tu + u\):
\[
tu + u = 5 + 5 = 10
\]

3. Now substitute this result back into the original expression:
\[
-10 / (tu + u) = -10 / 10
\]

4. Finally, simplify:
\[
-10 / 10 = -1
\]

The simplified answer is \(-1\).
