10cm=10 * 10^-2 = 10^-1 meters
so its 2 meters + 0.1 meters = 2.1 meters
Direct variation is of the form
y= mx
2x-4y = 0
2x = 4y
4y = 2x
y = 2/4 x
y =(1/2)x
which is indeed of the form y = mx
Hence, the equation does represent direct variation.
in y= mx,
the constant of variation is m
so in y = (1/2)x
the constant of variation is 1/2
Equation changes to 4x+(8 x .8)= 40. changes to 4x+6.4=40. subtract 6.4 from fourty, and you get 33.6. then you divide 33.6 by 4 and you get 8.4
x=4
