Which of the following relations has a domain of {-2, 0, 5}? choose all that apply. {(-2, 5), (3, 4), (5, 1)} {(-2, 3), (0, 1), (-2, 4), (5, 4)} {(5, 6), (0, 4), (-2, 1)} {(4, -2), (3, 0), (2, 5)}

Second option: {}

Third option: {}

Step-by-step explanation:

By definition, the Domain of a relation is the set of all the x-coordinates of the ordered pairs (It is necessary to remember that the x-coordinate is the first element of the ordered pair).

Then, we know that the set of all the x-coordinates of the relation we need to find is: {}

First option {}:

Domain:  {}

Second option {}:

Domain:  {} (Notice that we do not need to write -2 twice)

Third option {}:

Domain:  {}

Fourth option {}:

Domain:  {}

The relations {} and {} has a Domain of  {}

3, 4, 5 triangle

Step-by-step explanation:

I'm assuming that the question is about which pythagorean triplet this triangle is? If so, then divide by 6 on all sides to get the 3,4,5 triple.
