It's the 2nd one

Step-by-step explanation:

To find the number of yellow marbles, you would do the number of blue marbles plus 6 marbles.

So in this case, let's say n was equal to the number of blue balls, the equation would be n+(n+6)=24.

What if n was equal to the number of yellow balls. The equation would be n+(n-6)=24.

Hope this made sense, let me know if you are still confused.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
