Answer:
D^1 should be (28,0) 
Step-by-step explanation:
a dilation is performed by multiplying the x and y coordinates by the scale factor. D(7,0)... (7×4,0×4).... D^1(28,0)
 
        
             
        
        
        
Negative 1 because 3 x 3 is 9 and -2 x 5 is -10. Therefore 9-10= negative 1
        
                    
             
        
        
        
Answer:
46800

46821 nearest 100s 
look for the tens it is less than 5 so its 800 and the numbers written before the 100s would remain the same 
 
        
             
        
        
        
Answer: 350
Step-by-step explanation:
Let the cheeseburger be represented by a.
Since there were 51 fewer cheeseburgers sold than hamburgers. This means that hamburgers will be:
= a + 51.
Since the local hamburger shop sold a combined total of 649 hamburgers and cheeseburgers. This will be:
a + a + 51 = 649
2a + 51 = 649
2a = 649 - 51
2a = 598
a = 598/2
a = 299
299 cheeseburger were sold
Therefore, the number of hamburger sold will be:
= 649 - 299
= 350
