Functions cannot have the same X value (the first number), but they can have the same Y value (the second number).
<span>A. {(1,2),(2,3),(3,4),(2,1),(1,0)}
B. {(2,−8),(6,4),(−3,9),(2,0),(−5,3)}
C. {(1,−3),(1,−1),(1,1),(1,3),(1,5)}
D. {(−2,5),(7,5),(−4,0),(3,1),(0,−6)}
Choice A. has two repeating X values [(1,2) and (1,0), (2,3) and (2,1)]
Choice B. has one repeating X value [(2, -8) and (2,0)]
Choice C. all has a repeating X value (1)
Choice D doesn't have any repeating X values.
In short, your answer would be choice D [</span><span>{(−2,5),(7,5),(−4,0),(3,1),(0,−6)}] because it does not have any repeating X values.</span>
Tickets are 24$ for 1 adult.
Two thirds of 24 will be the price of 1 child. Divide 24 by 3 and you get 8. Since 8 is 1/3 of 24, 16 would be 2/3 of 24.
So the price for 1 child is 16$.
2 adults and 2 children is 24+24+16+16
The family had to pay a total of $80
0.07 is 10 times as much as 0.007.
Because is means equal in mathematics
times means multiplication
so we can make:
0.07 = 10x
x = 0.007
