<em>1. x = - 7/3 = - 2 1/3</em>
<em>2. x = -2</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em />
<em>3x + 12 = - 6x - 9</em>
<em>3x + 6x = - 12 - 9</em>
<em>9x = - 21</em>
<em>x = - 21⁽³/9</em>
<em>x = - 7/3</em>
<em>x = - 2 1/3</em>
<em />
<em>12x + 20 = 2x</em>
<em>12x - 2x = - 20</em>
<em>10x = - 20</em>
<em>x = - 20/10</em>
<em>x = - 2</em>

<em>Good luck !</em>
Answer:
None of these.
Step-by-step explanation:
The sector angle is not given, therefore no conclusions about the choices involving points D,E and A,B with respect to each other, and C, F can be made.
<h2>Hello!</h2>
The answer is:
The relation is a function
Domain: {-5,-3,1}
Range: {6,3}
<h2>Why?</h2>
It's a function since each input (domain) has only one value at the output (range). A function exists when there is only a single value for each input, if there is more than one output for each input, the relation is not a function.
Have a nice day!
