Recursive equation would be f(x+1) = f(x) - 25 with f(0) = 300
Explicit equation would be f(x) = -25x + 300
And graph would looks like this: 
 
        
        
        
answer is (-7,2)
y = -x -5
y= x+9
Both equations have y on the left hand side
So we equate both equations
We replace -x-5 for  y in the second equation
 -x -5 = x+9
Subtract x on both sides
-2x -5 = 9
Now add 5 on both sides
-2x = 14
Divide by -2 from both sides
x = -7
Now plug in -7 for x in the first equation
y = -x -5
y = -(-7)  -5= 7-5 = 2
So answer is (-7,2)
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
372 + 1/4*372 = $465
$465 is her new savings and 33% of it is $153.45
$465 + $153.45 = $618.45 
So yes she would have enough money to buy a plane ticket to alaska the cost $600
 
        
             
        
        
        
-2m + 5 = 2m + 5
2m + 2m = 5 - 5
4m = 0
m = 0
 -2m + 5 = -2m + 5
-2m + 2m = 5 - 5
0 = 0
 -2m + 5 = -2m - 5
-2m + 2m = 5 + 5
0 = 10
Solution set is Ф
The third equation is the correct answer.
        
             
        
        
        
Answer:
A(10) = $13,961.50
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 5.25/100
r = 0.0525 rate per year,
Then solve the equation for A
The formula is given as:
A = Pe^rt
P = 8259
r = 0.0525
t = 10 years.
Hence, 
A = 8,259.00 × e^(0.0525×10)
A = $13,961.50
Therefore, the money that will be in the account after 10 years is $13,961.50
