Answer:
x=-4
Step-by-step explanation:
2(|x+4|+3)=6
take out absolute value
2(x+4+3)=6
remove parrenthesis 
2x+8+6=6
Simplify
2x+14=6
     -14  -14
2x=-8
x=-4
Hope this helps!!!!!
 
        
             
        
        
        
For the function 

We can use the formula for the axis of symetry, which is 

With the values substituted, we get...

Therefore the axis of symmetry is 
 
 
 
        
        
        
1. 0 - 34 + 13 - 5 = -26.....26 ft below the surface
2. y = 15x + 50
    220 = 15x + 50
    220 - 50 = 15x
    170 = 15x
    170/15 = x
    11 1/3 = x......he worked 11 1/3 hrs.......not sure about this...because it does not specify how many visits he made...but if this was just for 1 visit, then he worked 11 1/3 hrs
