1. Given that y = 5 / x + 5, judge the proportional relationship between Y and X, and explain the reason 2. Given that y = 5 / x, please judge the proportion of Y and X and explain the reason. 3. Give an example of positive and negative proportion in life!
1.y=(5/x)+5
Y and X are not directly proportional or inversely proportional. Y-5 is inversely proportional to X
2.y=5/x
Y is inversely proportional to x because xy = 5,5 is a constant that is not equal to 0
3. If the distance to school is fixed, the walking time is inversely proportional to the speed
