Question

Evaluate the expression for u = -1. Write your answer in the simplest form: (-3u + 5)/(5u).

Answer 1

To evaluate the expression (-3u + 5)/(5u) for u = -1, substitute -1 into the expression and simplify to get -1.6.

Step-by-step explanation:

To evaluate the expression for u = -1, we substitute -1 for u in the expression (-3u + 5) / (5u).

• First, we replace u with -1: (-3(-1) + 5) / (5(-1))
• Then, we simplify the numerator: (3 + 5) / (-5), which equals 8 / (-5).
• Finally, we reduce the fraction to its simplest form, which is -8/5 or -1.6.

The result of the expression for u = -1 is -1.6 in the simplest form.
