Final answer:
To have a negative value for the expression 5 - 5x, the value of x must be greater than 1.
Step-by-step explanation:
To have a negative value for the expression 5 - 5x, the value of x must be greater than 1. This is because when x is greater than 1, the product of 5x will be greater than 5, resulting in a negative value when subtracted from 5. For example, if x = 2, the expression becomes 5 - 10, which is equal to -5.
