Answer:
The second one, B
Step-by-step explanation:
Direct variation is when y=kx where y is directly proportional to x for a constant k
3y=6x
3/3y=6/3x
y=2x
Here k=2 , yes 3y=6x is a direct variation.
Answer:
c.
Step-by-step explanation:
Answer:
146
Step-by-step explanation:
substitute x = 2, y = 3 into the expression
4(2)³ + 2(2)(3) - 2(3) + 3(2)²(3)²
= 4(8) + 12 - 6 + 3(4)(9)
= 32 + 12 - 6 + 108
= 38 + 108
= 146
