Which describes a greater unit rate of change of yyy with respect to xxx, the equation y=4.5xy=4.5xy, equals, 4, point, 5, x or the table? xxx 222 444 666
yyy 999 181818 272727

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

answer4 to the second power is 16

and 4 to the third power is 64,

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
