Question

is this always true, sometimes true, or never true? a positive number - a positive number = a positive number

• sometimes true
• always true

1 pts
a golfer has a score of -2 after the first 14 holes. on each of the last 4 holes, the golfer scores -1. what is the golfer’s final score?
note: in golf, the goal is actually to get the lowest score possible. each hole has a \par,\ which is the number of strokes a good player is expected to take. if a player takes fewer strokes than par, their score becomes negative (for example, -1 means they took one stroke less than expected). this is a good thing! a higher score means more strokes were taken, which is not the goal. so in golf, a negative score is better than a positive one.

Explanation:

First Question (Is this always true, sometimes true, or never true? A positive number - a positive number = a positive number)

Step1: Analyze with examples

Case 1: Let the first positive number be \( 5 \) and the second be \( 3 \). Then \( 5 - 3 = 2 \) (positive). Case 2: Let the first positive number be \( 3 \) and the second be \( 5 \). Then \( 3 - 5 = -2 \) (negative).

Step2: Determine the truth value

Since there are cases where the result is positive and cases where it is not, the statement is sometimes true.

Step1: Calculate total score from last 4 holes

The golfer scores \( -1 \) on each of 4 holes. So total score from last 4 holes is \( 4\times(-1)= -4 \).

Step2: Add to initial score

Initial score is \( -2 \). Final score is \( -2 + (-4) = -6 \).

Answer:

Sometimes true
