Answer:
18 people ordered beer.
Step-by-step explanation:
15 + 3 = 18 people
11.k>-3(4r+3)/4r-5
12.k<(2x+2)/x+3
600 fish / 9 dolphins = 66.667
9 fish * 66 = 594 fish
600 fish - 594 fish = 6 fish
there are 6 fish left
A function is a special relationship where each input has a single output.
therefore :
A is not a function; x=0; ⇒y₁=3; y₂=4
C is not a function; x=2;⇒ y₁=1; y₂=8
D is not a function; x=1;⇒y₁=2, y₂=-3
only B is a function; each input has a single output.
