Answer:

C) 2(20)

Step-by-step explanation:

In a football game there are 2 teams playing against each other so there are 2 possible winners in a game as either of the 2 teams can win the game. So there are 2 ways to make prediction of winner for a game.

Since, there are 20 football games in total, and predictions of winner per each game are 2, so the possible predictions for 20 games would be 2 x 20

Hence, 2(20)=40 different predictions would be possible for 20 football games.

Domain of the function of a graph with coordinates (-3,-2)
olga2289 [7]

Answer:

Domain is -3

Step-by-step explanation:

Given that coordinate of a graph is (-3, -2)

We have to find out the domain.

We know that if A and B are two sets, a mapping from A to B is the subset of cartesian product AxB.

Domain is the set of values of A which have images in B.

Use the above definition.

We have A = {-3,...} and B = {-2,....}

The mapping is from -3 to -2

Hence domain is -3

ANSWER FAST <br> NO LINKS<br> 23=x-13<br><br> 9+x=14<br><br> 12=x+8
Anna35 [415]

Answer:

23=x-13, x=36

9+x=14, x=5

12=x+8, x=4

Step-by-step explanation:

23=x-13. You want to isolate x so you have to add 13 to both sides. x=23+13, x=36

9+x=14. You want to isolate x so you have to subtract 9 from both sides. x=14-9, x=5.

12=x+8. You want to isolate x so you have to subtract 8 from both sides. x=4.
