Does the equation 7x-4y=0 represent a direct variation? what is the constant of variation?

yes, k =

Step-by-step explanation:

The equation representing direct variation is

y = kx ← k is the constant of variation

rearrange 7x - 4y = 0 into this form

subtract 7x from both sides

- 4y = - 7x ( divide both sides by - 4 )

y = x ← in standard form

with k =

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
