Answer:
2. n = 11
4. g = -2
6. t = 21
8. n = 4
10. y = -1
Step-by-step explanation:
2. 63  = -3(1 - 2n)
Dividing both the side by negative 3 we get 

4. -g + 2(3 + g) = -4(g + 1)
First we will open the bracket by distributive property A( B +C) = AB + AC

6.-3(t +5 ) + (4t + 2) = 8
Using distributive property A( B +C) = AB + AC we get

8. -8 - n = -3(2n -4)
Using distributive property A( B +C) = AB + AC we get

10. -4( 2 - y) + 3y = 3(y - 4)
Using distributive property A( B +C) = AB + AC we get

 
        
             
        
        
        
It would first be 0.7 and then 1.1
        
                    
             
        
        
        
Answer:
   (x, y) ⇒ (x -7, y)
Step-by-step explanation:
The y-coordinates are unchanged. Each x-coordinate of the image is 7 units less than the corresponding pre-image coordinate. As a rule, this is ...
   (x, y) ⇒ (x -7, y)
