Answer:
a. 4y =12x the constant of variation is 3
Step-by-step explanation:
The equation for direct variation is y=kx
a. 4y =12x
Divide each side by 4
4y/4 = 12x/4
y = 3x
This is direct variation and the constant is 3
Equations b ,c, d all have a constant added which make them something other than a direct variation
Answer:
Step-by-step explanation:
x=-1-2y
-2-4y-3y-12=0
-7y=14
y=-2
x=3
1.64 / 0.2 = 8.2 I checked it to make sure by multipying: 8.2 * 0.2 = 1.64
