Answer:
10
Step-by-step explanation:
First, you would subtract 100-70 to get 30
Then, you would do 30/3 to learn that you could still buy 10 packs of Oreos with the remaining money.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
From the table given in the question,
x            y              Difference                  Ratio
1            12                     -                             -
2           36              36-12 = 24              
3          108            108-36 = 72             
4          324            324-108 = 216        
5          972            972-324 = 648      
There is a common ratio of 3 in each successive term.
Therefore, data given in the table will represent an exponential function.

For a point 

 ------(1)
 ------(1)
For another point of the table  ,
,

 --------(2)
 --------(2)
Equation (2) divided by equation (1)


From equation (1),


Therefore, exponential function will be,

Answer:
-2
Step-by-step explanation:
because the slope is 2, a perpendicular line must be the inverse  
the equation for y1 is y=2x+1
y2= -2y+1
