Oh its super easy! 5w = 5 x W, so take one of the numbers like 2 and times it by 5 and add it to the rest of the problem, and see if the number you get is in your answers, if its not, then try the others!
Answer:
No
Step-by-step explanation:
An equation is proportional only if it goes through the origin, meaning the if you plug in 0 for x, you should get 0 for y. In this case plugging in 0 for x gives us 2 for y, meaning it is not proportional.
4x(3x + 8) - 7y(5x - 1) =
12x^2 + 32x - 35xy + 7y
