Answer:

A

Step-by-step explanation:

It is possible because the dimensions of A is 3x1 and B is 1x3, and you can only multiply if the colums of A is equal to the rows of B which in this case is.

Then to multiply, you start from 1 and multiply with 5 then 0 then 4 and then multiply 5 (from A) with 5 (from B) and so on.

1(5)     1(0)     1(4)                                        5         0         4

5(5)    5(0)    5(4)                     =               25        0        20      

-3(5)   -3(0)   -3(4)                                      -15        0       -12

Hope this helps!

Which of the relations given by the following sets of ordered pairs is a function?
adell [148]
Functions cannot have the same X value (the first number), but they can have the same Y value (the second number).
<span>A. {(1,2),(2,3),(3,4),(2,1),(1,0)}
B. {(2,−8),(6,4),(−3,9),(2,0),(−5,3)}
C. {(1,−3),(1,−1),(1,1),(1,3),(1,5)}
D. {(−2,5),(7,5),(−4,0),(3,1),(0,−6)}

Choice A. has two repeating X values [(1,2) and (1,0), (2,3) and (2,1)]
Choice B. has one repeating X value [(2, -8) and (2,0)]
Choice C. all has a repeating X value (1)
Choice D doesn't have any repeating X values.

In short, your answer would be choice D [</span><span>{(−2,5),(7,5),(−4,0),(3,1),(0,−6)}] because it does not have any repeating X values.</span>
