Answer 2

To evaluate the expression (2x - 1) / x for different values of x, simply substitute each value of x into the expression and perform the calculations. Let's calculate the result for each given value of x:

1. When x = 3: (2 * 3 - 1) / 3 = (6 - 1) / 3 = 5 / 3 = 1.6666666666666667

2. When x = -5: (2 * -5 - 1) / -5 = (-10 - 1) / -5 = -11 / -5 = 2.2

3. When x = 1/2: (2 * (1/2) - 1) / (1/2) = (1 - 1) / (1/2) = 0 / (1/2) = 0

4. When x = -1.6: (2 * (-1.6) - 1) / (-1.6) = (-3.2 - 1) / (-1.6) = -4.2 / (-1.6) = 2.625

5. When x = 100: (2 * 100 - 1) / 100 = (200 - 1) / 100 = 199 / 100 = 1.99

So, the results for each value of x are: 1: 1.6666666666666667 -5: 2.2 1/2: 0 -1.6: 2.625 100: 1.99
