Can someone help please?

Mathematics
1 answer:
alina1380 [7]4 years ago
5 0

Answer:

(-1, 3)

Step-by-step explanation:

The given equation is 2x + y = 5.

Test whether (-1, 3) is a solution.  To do this, substitute -1 for x and 3 for y.  Does 2(-1) + 3 = 5?  No, it does not.  So this could be the correct answer choice.

Test whether (6, -7) is a solution.  Is 2(6) - 7 = 5 true?  Yes, it is.  So this is not a correct choice.

Test whether (3, -1) is a solution.  Is 2(3) -1 = 5?  Yes, it is.  So this is not a correct choice.

Summary:  The only answer choice that does NOT satisfy the given equation is the first one:  (-1, 3).

The answer would be D. H<span>ow long are the songs you practice playing on your instrument?

Statistical questions are ones that will show variability. The first three questions will have a straight answer. The last one however will have data that varies, since most likely every song is not the same length.
