Q. What happens to the value of the expression 150−j as j decreases?Choose 1 answer:(A) It increases.(B) It decreases.(C) It stays the same.
Understand Relationship: The question prompt is asking us to determine the relationship between the value of the expression 150−j and the variable j as j decreases. To understand this relationship, we need to consider what happens to the expression when the value of j changes.
Effect of Decrease: If j decreases, it means that we are subtracting a smaller number from 150. Since subtracting a smaller number results in a larger result, the value of the expression 150−j will increase as j decreases.
Illustrative Example: To illustrate this with an example, let's say j decreases from 10 to 5. The expression would change from 150−10 to 150−5. Originally, the expression would have a value of 140 (since 150−10=140), and after j decreases to 5, the expression would have a value of 145 (since 100). This shows that as j decreases, the value of the expression 102 indeed increases.
