For this case what you should know is that both functions are of the potential type.
 We have then that
 y = 2 * 2 ^ x This function grows exponentially upwards.
 y = -2 * 5 ^ x This function grows exponentially downwards.
 Answer See attached graphics.
 
        
        
        
Answer:
3,872.32
Step-by-step explanation:
the nearest hundredth is 2 numbers on the right of the decimal sign. So you round up from 5 to get answer above.
 
        
             
        
        
        
Answer:
$20.60
Step-by-step explanation:
25.75x20%=5.15
25.75-5.15=20.60
 
        
                    
             
        
        
        
Answer:
Extra snow needed > 0. 3 inch
Step-by-step explanation:
Given that:
Cancelation occurs when > 2.5 inch of snow accumulates each hour 
Accumulation rate = 11/5 inch per hour
Extra snow Accumulation needed to cancel. School ;
Extra snow needed > cancelation volume - current rate
Extra snow needed > (2.5 - 11/5)
Extra snow needed > 0. 3 inch 
 
        
             
        
        
        
Solve the top equation to get on variable on one side
2x-y=6
-y=-2x+6
y=2x-6
then plug in the coordinate for x and y for both equations. if both equations are true then it’s a solution
2=2(2)+6
2=10
4+2=6
so it’s not a solution
