Answer:

B. Reflect PQR across a horizontal line through R, and then translate the image so R aligns with Z.

Step-by-step explanation:

Imagine a horizontal line through point R. Once you reflect the triangle across this line, it will be facing the same direction as triangle XYZ. Then, once you align R with Z (they are corresponding points!) the triangles will be directly on top of each other.

3x+4y+6z=15<br>Solve for x.

aalyn [17]

Answer:

<h2> </h2><h2> $x = 5 - \frac{4}{3} y - 2z$ </h2>

Step-by-step explanation:

<h3><u>Question</u><u>:</u><u>-</u></h3>

To solve for x

<h3><u>Equation</u><u>:</u><u>-</u></h3>

3x + 4y + 6z = 15

<h3><u>Solution</u><u>:</u><u>-</u></h3>

=> 3x + 4y + 6z = 15

<em>[</em><em>On</em><em> </em><em>subtracting</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>4y</em><em>]</em>

=> 3x + 4y + 6z - 4y = 15 - 4y

<em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 3x + 6z = 15 - 4y

<em>[</em><em>On</em><em> </em><em>subtracting</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>6z</em><em>]</em>

=> 3x + 6z - 6z = 15 - 4y - 6z

<em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 3x = 15 - 4y - 6z

<em>[</em><em>On</em><em> </em><em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>3</em><em>]</em>

$= > \frac{3x}{3} = \frac{15 - 4y - 6z}{3}$

<em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

$= > x = 5 - \frac{4}{3} y - 2z \: (ans)$
