What is the sign of - 4x .y. 06 when X and Y are positive numbers? Choose 1

A. Positive
B. Negative
C. Zero

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

other answer is correct. i had used the radius of the radius somehow. a website:

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
