Answer:
Both
and
are solutions to the system.
Step-by-step explanation:
In order to determine whether the two given points represent solutions to our system of equations, we must "plug" thos points into both equations and check that the equality remains valid.
Step 1: Plug
into 

The solution verifies the equation.
Step 2: Plug
into 

The solution verifies both equations. Therefore,
is a solution to this system.
Now we must check if the second point is also valid.
Step 3: Plug
into 

Step 4: Plug
into 

The solution verifies both equations. Therefore,
is another solution to this system.
Texaschic nailed it when saying that it's arithmetic
The recursive way to write this is to say


which tells us "start at 6 and each time subtract off 5"
The

portion is the nth term while

is the term just before the nth term
4.2 +c = 8.1
c = 8.1 -4.2 = 3.9 . . . . subtract 4.2 from both sides
a.) 3.9 liters . . . . . is the appropriate choice
The answer to your question is 9.5
At first you need to know total cost (875)(1.05)=918.75According to the fact that you have already paid for 7 months, we have to subtract 700=218.75 what still needs to be payedOn the 8 moth you have missed the payment so (218.75)(8/12), and remaining moths are nearly 145.83333To finish, multiply by the apr and you will get $20.78 interest charged. So, I am pretty sure that he answer is D.
