A set of ordered pairs, like the ones shown, represents a function only if each of the first coordinates is not repeated.
For example {(2, 5), (7, 8)} is a function, but {(2, 3), (6, 8), (2, -1)} is not because 2 is repeated.
We can check that each set of pairs we are given, are functions.
The inverses of each of these sets would be :
<span>{(–2, –1), (4, 0), (3, 1), (14, 5), (4, 7)} 4 repeats
{(2, -1), (4, 0), (5, 1), (4, 5), (2, 7)} 4 and 2 repeat
{(3, -1), (4, 0), (14, 1), (6, 5), (2, 7)} no repetition of 1st coordinates
{(4, -1), (4, 0), (2, 1), (3, 5), (1, 7)} 4 repeats
</span>
So only the inverse of <span>{(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} is also a function</span>
Answer:
i'm not 100% sure but i think it is C
Step-by-step explanation:
Hello!
We know our denominator is 60, because that is the total amount of cities. Now, we must find our numerator:
3 + 29 = 32
Fraction: 32/60
You can simplify this by dividing both the numerator and denominator by 4:
32 ÷ 4 = 8 60 ÷ 4 = 15
FRACTION (SIMPLIFIED): 8/15
Solutions
You have been given the y-intercept of -4. The meaning of this is that the given line will go through the point (0, -4). Plug in 1 for x and find y.

<span>Graph C is the correct answer.</span>
Answer:
the first one is 18/32 and the second one is 125 games or 120
Step-by-step explanation:
for the first add all the numbers to get your denominator then add the probability of green aND YELLOW.
for the second you just divide 200 by eight to get 25 then times 25 by 5 to get your anwser
hope this helped :)
