Answer:
value of blue dot is -6
Step-by-step explanation:
-6 is visible if you go 3 units to the left of -3. -3 - 3 = -6.
 
        
             
        
        
        
Hello!
So, the slope is 2, which means "up 2 over 1" because of rise over run and 2 is 2/1.  
You have to find the graph that as a line passing through (-2, -3), so the answer is going to be Graph D. 
Hope this helps :))
        
                    
             
        
        
        
X^2 - 6x = 20
x^2 - 6x + 9 = 20 + 9
(x - 3)^2 = 29
x - 3 = (+-) sqrt 29
x = 3 (+-) sqrt 29
x = 3 (+-) 5.39
x = 3 + 5.39 = 8.39 <=
x = 3 - 5.39 = - 2.39 <=
        
                    
             
        
        
        
Answer:
1) Rizza's average speed is 27 km/h.
2) The distance between Barretto and Pampanga is 294 km.
3) Aaron's journey was 3.5 hours long.
Step-by-step explanation:
1) Time taken to cove the distance = 20 minutes
60 minutes = 1 hour
So that, 20 minutes =  hours
 hours
                                  =  hours
 hours
Distance covered = 9 km 
But,
speed = 
Rizza's average speed = 9 ÷ 
                                        = 9 x 3
                                        = 27 km/h
Rizza's average speed is 27 km/h.
2) Time taken = 3.5 h 
the car's average speed = 84 km/h
Distance between Barretto and Pampanga = average speed x time taken
                                            = 84 km/h x 3.5 h
                                            = 294 km
The distance between Baretto and Pampanga is 294 km.
3) The uniform speed implies that Aaron did not accelerate during his journey.
Distance covered = 210 km
uniform speed = 60 km/h
time taken = 
                    = 
                    = 3.5 hours
Aaron's journey was 3.5 hours long.
