Neko [114]

Answer:

8.005 km

Step-by-step explanation:

There are 1000 meters in a kilometer, so:

5/1000 = 1/200 = 0.005

8 km + 0.005 km = 8.005 km

Which line is parallel to the line 8x + 2y = 127

fomenos

Solve for y, add 8x to the other side then when y is isolated divide both sides of the question by two and that should give you your final equation and you should have the slope and yint

A(3,4),B(5,8),C(7,8) are the vertices of ABC, prove that the line passing through the mid point of AB and AC is parallel to BC

Ede4ka [16]

<h2>Explanation:</h2><h2></h2>

$The \ midpoint \ formula \ of \ the \ line \ segment \\ that \ joins \ the \ two \ points \ (x_{1},y_{1}) \ and \ (x_{2},y_{2}) \ is \\ given \ by \ the \ following \ Midpoint \ Formula:\\ \\ Midpoint=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$

Let's name the mid point of $AB$ as $c$

Let's name the mid point of $AC$ as $p$

Then:

$c=(\frac{3+5}{2},\frac{4+8}{2}) \\ \\ c=(\frac{8}{2},\frac{12}{2}) \\ \\ c=(4,6) \\ \\ \\ p=(\frac{3+7}{2},\frac{4+8}{2}) \\ \\ p=(\frac{10}{2},\frac{12}{2}) \\ \\ p=(5,6)$

So the slope of the line that passes through $c \ and \ p$ is:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m_{cp}=\frac{6-6}{5-4}=0$

And the slope for BC is:

$m_{BC}=\frac{8-8}{7-5}=0$

As you can see, both slopes are zero, so these are horizontal lines.
