What are the coordinates of the point on the directed line segment from (-6, -3)(−6,−3) to (-1, 7)(−1,7) that partitions the seg

rosijanka [135]

Answer:

(-3,3).

Step-by-step explanation:

The given points are (-6,-3) and (-1,7).

We need to find the coordinates of the point, which divides the line segment in 3:2.

Section formula: If a point divides a line in m:n, then the coordinates of point are

$\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)$

Using this formula, we get

$\left(\dfrac{3(-1)+2(-6)}{3+2},\dfrac{3(7)+2(-3)}{3+2}\right)$

$\left(\dfrac{-3-12}{5},\dfrac{21-6}{5}\right)$

$\left(\dfrac{-15}{5},\dfrac{15}{5}\right)$

$\left(-3,3\right)$

Therefore, the coordinates of required point are (-3,3).

Question is: Solve -7(x+6)=4(x+6)

Alina [70]

$\huge\boxed{x=-6}$

Hey there! Our goal here is to isolate the variable on one side of the equation.

$\begin{aligned}-7(x+6)&=4(x+6)&&\smash{\Big|}&&\textsf{Start with the original equation.}\\-7x+(-7)(6)&=4x+4(6)&&\smash{\Big|}&&\textsf{Distribute.}\\-7x-42&=4x+24&&\smash{\Big|}&&\textsf{Multiply.}\\-7x-4x&=24+42&&\smash{\Big|}&&\textsf{Move the terms.}\\-11x&=66&&\smash{\Big|}&&\textsf{Combine like terms.}\\x&=\boxed{-6}&&\smash{\Big|}&&\textsf{Divide both sides by $-11$.}\end{aligned}$
