Answer:

<em>B=-3</em>

Step-by-step explanation:

<em>-11b+7=40</em>

<em />

<em>Subtract -7 from both sides</em>

<em />

<em>-11b-7=40-7</em>

<em />

<em>11b=33</em>

<em />

<em>divide by -11</em>

<em />

<em>11b/-11=33/-11</em>

<em />

<em>-11 and -11 cancel out, leaving you with B=-33/11</em>

<em />

thus B=-3

Step-by-step explanation:

subtract 7 on both sides

40-7=33

-11b=33

b=-3

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})

<h2></h2>
  • 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.
