The equation that models the sequence is: 6+6 each time.
This should have been worth more points, but anyways, here are the answers. Please give thanks :)
1.)Y = 5 - 3X<span>
2.) Y= </span><span>3X - 4</span><span>
3.) Y = 7 - X
4.) Y = -5X
5.) Y = </span>X +6 <span>
6.) Y = 5 -3X
7.) Y = 2 +</span>

<span>X
8.) </span>Y =

X - 3<span>
9.) Y= 2 - [</span>tex] \frac{2}{3} [/tex]<span>
10.) Y = 1 - 5X
11.) Y = 2 - </span>

<span>X
12.) Y = -5 -2X
13.) Y = X - 6
14.) Y = </span>

<span> -2X
15.) Y = 2 +</span>

<span>X
16.) Y = 2 +</span>

<span>X
17.) Y = 1 - 5X
18.) Y = </span>[<span>tex] \frac{3}{4} [/tex]</span>X + 2
A <span>dodecagon has 12 sides
Sum of the interior angles = (12 - 2) x 180 = 1800</span>°
One interior angle = 1800 ÷ 12 = 150°
-------------------------------
Answer : 150°
------------------------------
Its either A or B because the numbers are const but there also increasing hopes this helps
