Hi there!

Evalute by substituting in 5 for x:
w(5) = 9(5) + 8 
Simplify:
w(5) = 45 + 8 = 53
 
        
                    
             
        
        
        
You are only showing one pair of triangles
        
             
        
        
        
The inequality x < 9.7 tells us x needs to smaller than 9.7.
A number like 5 will be fine. Because 5 < 9.
But someone like 10 won't be fine.
Because 9 < 10.
Even 9.7 won't be suffice.
Because 9.7 < 9.7 does not make sense. If it was 9.7 <= 9.7 then it would be fine.
