Q. What happens to the value of the expression 20q as q decreases?Choose 1 answer:(A) It increases.(B) It decreases.(C) It stays the same.
Analysis of the expression: Let's analyze the expression (q)/(20). This is a direct proportionality between q and the value of the expression. As q changes, the value of the expression will change in the same direction because the denominator, 20, is a constant positive number.
Effect of decreasing q: Now, let's consider what happens when q decreases. Since q is in the numerator, if we decrease q, the overall value of the fraction20q will also decrease. This is because we are dividing a smaller number by the same positive constant.
Confirmation through example: To confirm our reasoning, we can think of a simple example. If q decreases from 20 to 10, the value of the expression changes from (20)/(20)=1 to (10)/(20)=0.5. Clearly, the value of the expression has decreased.
