(10/3)z = (y-6)^2

y = sqrt[(10/3)z] +6

= 1.826 sqrt z + 6

I'm sorry. Really don't understand this. Where did the 10/3 come from in the first step?

**bobpursley**, Friday, November 20, 2009 at 10:20am.3 is 3/10

if you move that across the equal sign, you get

z=3/10 sqrt( )

10/3 z= sqrt ( )

then square both sides

(10/3 z)^2=y-6

y= (10/3 z)^2+6
