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.
It is 7.5, think like 100÷4
Since you didn't offer potential answer choices, here's a sample answer which would work for this scenario. Using this, you can compare it to the choices that you have to make a decision.
Sample Answer:
Bob opened savings account with $200. Every week since, he has added $139 into it.
Easy
if x is the number
sqrt x is between 17 and 18
17<√x<18
squaer the whole thing
289<x<324
x could be 300
it could be sqrt of 300
√300=10√3
one is 10√3
Answer:
<em>The National football league has </em><em>464 more players</em><em> than the Major League baseball.</em>
Step-by-step explanation:
Since there are 30 teams in the Major league baseball and there are 40 players in each team, this means that the total number of players in the Major league baseball is:
30 × 40 = 1200 players
Since there are 32 teams in the National football league and there are 52 players in each team, this means that the total number of players in the National football league is:
32 × 52 = 1664 players
Therefore, the difference in the number of players in both leagues is:
<em>1664 - 1200 = 464 players</em>
<em></em>
Therefore, the National football league has <em>464 more players</em> than the Major League baseball.
