from both sides of the equation.

Answer:

Apply the distributive property.

6 ⋅ 5 + 6 (-3x) = -4 x - 12

Multiply

6 by 5 . 30 + 6 (-3 x) = - 4 x - 12

Multiply

− 3 by 6 . 30 - 18 x = - 4 x - 12

Add

4 x to both sides of the equation.

30 - 18 x + 4 x = - 12

Add

− 18 x and 4 x . 30 - 14 x = - 12

Subtract

30

from both sides of the equation.

- 14 x = - 12 - 30

Subtract

30 from

− 12 . - 14 x = - 42

x = 3

Find the midpoint of the segment having endpoints (0 ,1/8) and (-4/5 ,0)
kvasek [131]

Answer:

Mid point of the given end points = (\frac{-2}{5},\frac{1}{16} )

Step-by-step explanation:

Given the end points of the line segment are :

(0, \frac{1}{8}) & (\frac{-4}{5},0)

We will use the mid point formula when two points are: (x₁,y₁) & (x₂,y₂)

mid point = (\frac{x_{1} +x_{2} }{2},\frac{y_{1} +y_{2} }{2} )

now put the value of x₁ = 0

x₂ = \frac{-4}{5}

y₁ = \frac{1}{8}

y₂ = 0

mid point = (\frac{0-\frac{4}{5} }{2},\frac{\frac{1}{8}+0 }{2})

                = (\frac{-2}{5},\frac{1}{16} )

That's the final answer.
