On the windowsill is a plant that is 2 inches tall. It is growing 3 inches per week. A second plant, which is 11 inches tall, is on the coffee table. It is
growing 2 inches per week. Eventually the two plants will be the same height. How tall will the plants be? How many weeks will that take? Solve using substitution.

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

the answer is a

step-by-step explanation:

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
