Answer:
y=4
Step-by-step explanation:
its asking which one you can answer without any more context, in this case its y=4 because all the other ones evolving x lead to a rabbit hole and will take you in circles.
y=x
direct variation form is y = kx where 'k' is the constant of variation
y=4 This has no 'x' variable
y = 1/3x+4 The constant of variation is 1/3 but then 4 is added, so no direct
y = x³ The 'x' variable must be to the power of one
525
5 percent of 500 is 25
25 + 500=525
