Simplify 3 ∙ 2x. what is the coefficient?
a)2
b)3
c)6
d)x

The simplification of 3 . 2x is 6x and coefficient is 6 .

Option (C) is correct .

Step-by-step explanation:

As given

= 3 . 2x

This is also written as

= 3 × 2x

= 6x

Definition of coefficient

Any number which is multiply by variable is called coefficient .

Thus 6 is the coefficient .

Therefore the simplification of 3 . 2x is 6x and coefficient is 6 .

Option (C) is correct .

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
