28 + vector b   = -12
vector b  = -40  
vector b has magnitude 40 units in the negative y direction.
 
        
             
        
        
        
Answer:
The slope is -3
Step-by-step explanation:
The formula is y= mx + b
m = slope
b=  y intercept
Therefore, the slope is -3
 
        
             
        
        
        
9 x 8 = 72
155 - 72 = 83
83 divided by 6 =13.8
So he has to make at least 14 deliveries in order to reach his goal.
        
                    
             
        
        
        
Answer:
3. 10000
Step-by-step explanation:
Given the following :
Number of gumball cartons = 3
Number of boxes per carton = 100
Number of gumballs per box = 100
The number of gumballs can be expressed in the form : (a. 10) ; where ; a = prime number ; b = whole number 
Values of a and b? 
Total number of gumballs :
Number of carton × number of boxes per carton × number of gumballs per box
3 × 100 × 100
Hence, writing the expression in the form: a. 10
a. 10 = 3 × 10000
