$\{ -2, 4, 5, 9 \}$

<h3>Step-by-step explanation:</h3>

The Domain of a Relation is just the set of the $x$ values of the ordered pairs in the relation (Recall that if you have an ordered pair, $(a,b)$ , $a$ is the $x$ value).

We are given the relation: $\{(9,-2),(-2,-10),(5,-9),(4,5) \}$ . The Domain of this relation is $\{ 9, -2, 5, 4 \}$ .

cricket20 [7]

Answer:

The 12 pack has a better value.

Step-by-step explanation:

1. create a ratio table.

you want to know how much the 4 pack would cost if it was a 12 pack.

you can see the ratio table in the picture above.

As you can see, when the 4 pack equals $7.68, making it a 12 pack will equal $23.04.

Then, compare 23.04 to 22.32.

In conclusion, the 12 pack has a better value.

A hockey player is offered two options for a contract: either a base salary of 50,000 and 1000 per goal, or a base salary of 40,

Rama09 [41]

The hockey player must score 20 goals in order to make the same money as the first contract

Solution:

Given that, hockey player is offered two options for a contract

Let "x" be the number of goals made

Option 1 :

A base salary of 50,000 and 1000 per goal

Money earned = 50000 + 1000(number of goals)

Money earned = 50000 + 1000x ------- eqn 1

Option 2 :

Base salary of 40,000 and 1500 per goal

Money earned = 40000 + 1500(number of goals)

Money earned = 40000 + 1500x --------- eqn 2

To make the same money as the first contract, eqn 1 must be equal to eqn 2

50000 + 1000x = 40000 + 1500x

1500x - 1000x = 50000 - 40000

500x = 10000

x = 20

Thus he must score 20 goals in order to make the same money as the first contract
