Answer:

x=105

y=150

Step-by-step explanation:

Systematic solution:

\left \{ {{x+y=255} \atop {x+5y=855}} \right.

\left \{ {x=255-y} \atop {x+5y=855} \right.

255-y+5y=855

4y=600

y=150

x=255-150=100

Answer:

C - The relationship represents a function because each input gives one unique output.

Step-by-step explanation:

To see if it is a function we can do the line test where we have a vertical line and "drag" it along the line. As long as it only hits the line once in every situation it is a function! We can see this passes and therefore the answer is c.

(why is it not d? you can have a non-linear line, but still have a function)
