Abe's horse is travelling at the speed of 6 miles per hour.
Which set of ordered pairs represents a function? {(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)} {(3, –1), (7, 1), (–6, –1), (9, 1

A function can't have x repeating any of the same number twice for example the first one (2, -2), (1, 5), (-2, 2), (1,-3), (8,-1) you have two 1's (1,5) and (1,-3) the x is the first number. Now a function can have the same y value. So your answer is (3, -1), (7,1), (-6,-1), (9,1), and (2,-1) you have to have all different x values in order for it to be a function. Hope that helps.
Answer:
F. Lou Gehrig
Step-by-step explanation:
1 Mickey Mantle = 3 Babe Ruth
, therefore:
2 Lou Gehrig = 8 Ted Williams
, therefore:
4 Mickey Mantle = 6 Hank Aaron
, therefore:
4 Ted Williams = 12 Hank Aaron, therefore:
If:
4 Mickey Mantle = 6 Hank Aaron
Then multiplying by 2:
- 8 Mickey Mantle = 12 Hank Aaron
- Recall: 4 Ted Williams = 12 Hank Aaron
Then comparing:
4 Ted Williams=8 Mickey Mantle which means Ted Williams>Mickey Mantle
Now, we can attempt to order them:
- Ted Williams>Mickey Mantle
Lou Gehrig>Ted Williams>Mickey Mantle>(Hank Aaron and Babe Ruth)
We can see that since Lou Gehrig>Ted Williams, then the Lou Gehrig's card is the most valuable.
