What are the domain and range of each relation? Drag the answer into the box to match each relation. A mapping diagram. Element
ra1l [238]

Answer:

Domain: {−2, −1, 0, 2} Range: {−4, −2, 2}

Step-by-step explanation:

We have been given a mapping diagram as shown below:

X Y

-2 -4

-1 -2

0 2

2


For better view, you can check the attached mapping diagram.

From that diagram we have to find domain and range.

Domain contains only x values so domain will be:

Domain: {-2,-1,0,2}

Range contains only y values so range will be:

Range: {-4,-2,2}

We see that only third choice matches obtained values of domain and range.

Hence final answer is  Domain: {−2, −1, 0, 2} Range: {−4, −2, 2}

Mr. Inahurry sold his house for $27,000, which is a 10% loss over what he originally paid for it. What did he pay for the house
Ainat [17]

Answer: $30,000

Step-by-step explanation:

If Mr. Inahurry had a 10% loss, it means that he paid X for the house and only got back 90% (100% - 10%) of what he paid.

This way X . 90% = 27,000

               X . 0.90 = 27,000

               X = 27,000/0.9

               X = 30,000

Counter-proof: 30,000 . 10% = 30,000 . 0.10 = 3,000

                          30,000 - 3,000 = 27,000
