Hello,

First, you distribute: 
<span><span>−<span>7x</span></span>+<span><span>(<span>−3</span>)</span><span>(9)</span></span></span>+<span><span>(<span>−3</span>)</span><span>(<span>−<span>7x</span></span>) and it turns into </span></span><span><span><span>−<span>7x</span></span>+</span>−27</span>+<span>21<span>x

</span></span>Next, you must combine like terms:
 <span><span>−<span>7x</span></span>+<span>−27</span></span>+<span>21x = </span><span>(<span><span>−<span>7x</span></span>+<span>21x</span></span>)</span>+<span>(<span>−27</span>) = </span><span>14x</span>+<span>−<span>27

So, 14x-27 is your total answer.

I hope I helped :)</span></span>

Refer to the figure.
yuradex [85]

Answer:

b. line j or MT

Step-by-step explanation:

as the plane contains the points Q, N, P, R, T also the lines connecting only these points are in the plane, and are not intersecting the plane.

only M is outside of the plane, and so (only) the connecting line MT intersects the plane (at point T).

by the way, the question means the line RQ and not RO, as there is no point O in the graphic.

Easy, use these two formulas, to find Markdown:

Markdown=Original-New
and
Markdown%=\frac{Markdown Amount}{Original Selling Price} *100

So, plug in what you know.

Markdown= $30-$20.10
M=$9.90

Now, Markdown%

Markdown%=\frac{9.90}{30} *100
M%=0.33*100
M%=33

Thus, there was a 33% markdown.

As the input is increased by 1.

4 / (1/4) = 4 * 4 = 16

64/4 = 16

1024/64 = 16

So we can see the output factor is increased by a factor of 16.

Hope this helps.
