Question

Will the value of the expression 20−x increase, decrease, or stay the same as x increases? Explain.

Answer 1

Answer:

Step-by-step explanation:

Given the expression 20 - x.

The value of x determines if the value of the expression would increase, decrease or stay the same. When the value of x decreases, the value of 20 - x increases. When the value of x increases, the value of 20 - x decreases. And when the value of x does not change, 20 - x remains the same.

When greater values of x is subtracted from 20, you will have lower value left. Therefore, as x increases, the value of the expression 20 - x will decrease.
