6) Consider the following cube: Volume:
125 units3
a) What is the length of each side? Explain how you know.
b) Recall that the volume of a cube is found by taking the cube of its side length. The formula
that describes this is V=s3. Here we know that V=125. Write an equation that can be used to
find the side length.
c) To solve the equation, take the cube root of each side. How many solutions are there this time?
Explain why.
7) Find the solutions to the equation 27

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

answer:

your answer is: c. 196 7/8 in^3.

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
