Replace x with 2 and solve:
3(2)^3 - 4(2)^2 +2-1 = 9
answer is E none of these
A direct variation equation is in the form y = kx. So if you solve this equation will you get it in that form? No you will get y = 16/x. This is an inverse variation.
If you have 3/5 marbles and you got 4/3more marbles then all you have to do is:3/5 x 3/3 and get 9/15.For 4/3 you multiply 4/3 x 5/5 and get 20/15.You simplify this and get 1 5/15.Now all you do is add them and get 1 14/15. Hope this helped you :-).
Distance southward = 6x = 400, so x=66.66
total distance = 7x+x=8x = 533.33m
9/100, let me know if this helps.
