The ratio ⅖ to ⅓ has a unit rate of 2/15? true or false

What is the range of the relation in the table below? x y –2 0 –1 2 0 4 1 2 2 0

If 7x=9y, y/z = 7/5 , then x/z = (a) 2/7 (b) 7/9 (c) 9/5 (d) 9/7 (e) 5/9

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
