Answer:

9 cm

Step-by-step explanation:

the volume of a cube is x^3

x being for each side

so you would take the cube root of 729

which is 9

(9*9*9=729)

The equation of line L is y=5x+1
Nookie1986 [14]

Consider the complete question is "The equation of the line L_1 is y=5x+1 and the equation of line L_2 is 2y-10x+3=0. How can you show that these two lines are parallel?"

Given:

Equation of L_1 is y=5x+1.

Equation of L_2 is 2y-10x+3=0.

To show:

The these line as parallel.

Solution:

We have,

y=5x+1        ...(i)

2y-10x+3=0      ...(ii)

Equation (ii) can be written as

2y=10x-3

y=\dfrac{10x-3}{2}

y=\dfrac{10x}{2}-\dfrac{3}{2}

y=5x-\dfrac{3}{2}           ...(iii)

Slope intercept form of a line is

y=mx+b          ...(iv)

where, m is slope and b is y-intercept.

On comparing (i) with (iv), we get slope of line L_1.

m_1=5

On comparing (iii) with (iv), we get slope of line L_2.

m_2=5

Since, m_1=m_2, therefore, lines L_1 and L_2 and parallel because slope of two parallel lines are always equal.

Hence proved.
