Final answer:
To evaluate the given expression for different values of x, we substitute the values and perform the calculations. Substituting x = 3.4, x = 5, and x = 7.2 into the expression results in 15, 23, and 34, respectively.
Step-by-step explanation:
To evaluate the expression for x = 3.4, x = 5, and x = 7.2, we substitute these values into the given expression and perform the calculations. Let's consider a general expression as an example:
Evaluate: 5x - 2
- For x = 3.4, substitute it in the expression: 5(3.4) - 2 = 17 - 2 = 15
- For x = 5, substitute it in the expression: 5(5) - 2 = 25 - 2 = 23
- For x = 7.2, substitute it in the expression: 5(7.2) - 2 = 36 - 2 = 34
