How can I find x? Click for picture.

Answer:   You add up all the terms given of EACH angle, and make this an addition problem that is "equal to 180" ; since all triangles have three angles that add up to 180 degrees.  Then you solve for "x".
__________________________________________________
(as follows) ;  to get:    " x = 29 ⅔ ° " .
_______________________________________

         3x + 4 + 2x + x + 8 = 180  ;
_______________________________________
Combine the "like terms" ;

         3x + 2x + x = 6x ;

                 4 + 8 = 12

So, we have:  6x + 12 = 180 ;

Now, subtract "12" from each side of the equation:
__________________________________________
  6x + 12 − 12 = 180 <span>− 12 ;
</span>__________________________________________
 to get: 

      6x = 178 ;

Now, divide EACH SIDE of the equation by "6" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________________
    6x / 6 = 178 / 6 ;

to get:  x = 178/6 = 29 ⅔ ° .
______________________________________
             x = 29 ⅔ ° .

Graph y is less than or equal to 3
telo118 [61]
It would be a horizontal line (dotted line) at the y intercept 3. Make a line 3 units up, and it is dotted. Shade below the dotted line, to show the "less than" part. Hope this helps

Please help me if you can, thank you so much

D)

The slope (number with x variable) is negative because the line points down.

The y intercept is currently at 1.. if shifted up 2 units it would be at 3
