What is it? A or B I've been stuck for a while please help

Correct choice: B

Step-by-step explanation:

System of non-linear equations

It's given the following system of equations:

We'll use the substitution method. Substituting y from the first equation into the second equation, we have:

Moving all terms to the left side:

Simplifying:

Factoring:

There are two solutions:

x=-4, x=2

The first solution gives a value for y:

y=-4+13=9

First solution: (-4,9)

The second solution gives a value for y:

y=2+13=15

Second solution: (2,15)

Correct choice: B

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!

-une, your fren : )

one set of data has more variation than the other. hope this !
