Answer:
It is increasing before x = -2 and from x = 0 to x = 2
Step-by-step explanation:
Option 1 - you can see the line going down starting at -2 and that means the line is decreasing but the choice says "It is increasing before x = 0". This contradicts the actual graph.
Option 2 - The line isn't increasing before x= -1, it's actually decreasing as seen in the graph.
Option 3 - The line doesn't even touch the point before x = -3 so this choice makes no sense.
Option 4 - Since all the other choices were eliminated this is the only choice standing. Looking at the line it is increasing before x = -2.
 
        
             
        
        
        
Answer:
x=49
Step-by-step explanation:
los 3 angulos del triangulo deben de sumar 180
76+55=131
180-131=49
76+55+49=180
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
False. 
intersects the y-axis => x=0
tan (0+ π/6) = tan π/6 = 0.58
instead of 1.73
