Answer:
x-2y=0 is a direct variation
Step-by-step explanation:
Direct variation is of the form
y= kx
Can we get the equation in that form
x-2y =0
Add 2y to each side
x-2y+2y =0_2y
x=2y
Divide each side by 2
x/2 = 2y/2
1/2x =y
Flip the sides
y = 1/2x
This is of the form y= kx where k = 1/2
x-2y=0 is a direct variation
Answer:
IJ= 27
Step-by-step explanation:
HI+IJ=HJ
x+2x+9=4x
combine like terms
x=9
IJ=2(9)+9
18+9=27
IJ=27
