Apply the power of a power property to simplify
(y 4/3 •y 2/3)-1/2 =(y^2)-1/2= ?

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

The answers are 20,30,80,180,960,890,1230,4560. on the first row
