The relationship between V, the volume of a cube, and E, the length of each edge of the cube, is shown below. 3/V= E
E
What is the length, in inches, of each edge of a cube that has a volume of 64 cubic inches?

4 inches.

Step-by-step explanation:

Given: The relationship between V, the volume of a cube, and E, the length of each edge of the cube is given by :-

If volume = 64 cubic inches, then put V= 64, we get

Hence, the length of each edge of a cube =   4 inches.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
