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
The distributive property is when the coefficient in front of the parentheses is applied to both terms inside.
a. distribute the 6 to make 6xa+6x5. simplify to make 6a+30
b. distribute the 12 to make 12x4+12x3a. simplify to make 48+36a
c. distribute the c to make (1/2)xb-(1/2)x12. simplify to make (b/2)-6
