As the value of n decreases, the value of the expression, n + 15 also: B. decreases.
Given the algebraic expression, n + 15
We are required to determine what will happen to the value of the expression as variable n decreases in value.
To perfectly determine what will happen, we are going to plug in different values of variable n from the largest to the least and see what happens to the value of "n + 15".
Thus, let's use 3, 2, and 1.
- Plug in n = 3 into n + 15.
n + 15 = 3 + 15 = 18
- Plug in n = 2 into n + 15.
n + 15 = 2 + 15 = 17
- Plug in n = 1 into n + 15.
n + 15 = 1 + 15 = 16
Therefore, we can conclude that, as the value of n decreases, the value of the expression, n + 15 also: B. decreases.
