Answer:
(1,1)
Step-by-step explanation:
we have
 ----> equation A
 ----> equation A
 ----> equation B
 ----> equation B
we know that
The solution of the system of equations is the intersection point both graphs
The intersection point both graphs is the point (1,1)
see the given graph
therefore
The solution is the point (1,1)
Remember that 
if a ordered pair is a solution of a system of equations then the ordered pair must satisfy both equations of the system
<u><em>Verify</em></u>
Substitute the value of x=1 and y=1 in each equation and analyze the result
<em>Equation A</em>

 ---> is true
 ---> is true
so
The ordered pair satisfy the equation A
<em>Equation B</em>
 ---> is true
 ---> is true
so
The ordered pair satisfy the equation B
therefore
The ordered pair (1,1) is a solution of the system because satisfy both equations
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Given: Marisa bought four bottles
           Price of each bottle is $0.95.
Solving with the factors as given to find the total cost paid by Marisa.
Total cost= 
∴ Total cost paid by Marisa is $3.8.
As given to write an equation with the same product as the total cost but different factors.
∴ Lets assume the number of bottles bought by Marisa be "5" and cost of each bottle be "x"
We already find the total cost she paid is $3.8.
Now, writing an equation with different factors, as total cost remain same.

Dividing both side by 5
we get x= $ 0.76
∴ The required equation is 
 
        
             
        
        
        
Answer:
2 yrs
Step-by-step explanation:
SI =PTR/100
738=8200 x T x 4.5 /100
738 x 100 / 8200 x 4.5 = T
T =2
