Answer:
Concave down
Y-intercept: (0,-3)
X-intercepts: (-1,0) (-3,0)
Vertex: (-2,1)
 
        
             
        
        
        
We have y = -2 - 2x ;
Then, x + ( -2 - 2x ) = 5 ;
x - 2 - 2x = 5;
- x - 2 = 5 ;
-x = 7 ;
x = - 7;
Finally, y = - 2  - 2 × ( - 7 ) ;
y = - 2 + 14 ;
y = 12;
<span>The x coordinate of the solution to the system is - 7 .</span>
        
             
        
        
        
Answer:
A. 17.5
Step-by-step explanation:
 4x+8 27
L-------------M-------------------------N
<------------------ 6x -------------------->
 
LM = 4x+8
MN = 27
LN = 6x
 
LM + MN = LN
 
4x+8 + 27 = 6x
 
35 = 2x
 
17.5 = x
