Finding x:
If y=2x+9, substitute y into the equation x-3y=-12.
You will get: x-3(2x+9)=-12
Now, distribute: x-6x-27=-12
Add like terms: -5x-27=-12
Add 27 to both sides: -5x=15
Divide both sides by -5: x=-3
Now, substitute this value of x into the equation to find y: y=2(-3)+9
Multiply: y=-6+9
Add: y=3
Here is the solution: (x,y)=(-3,3)

Step-by-step explanation:
Answer: 15,384.60 is the price before the car was decreased by 9%.
You can verify this by doing the following:
15,384.60 x 9% (.09) = 1,384.615
15,384.60 (original price) - 1,384.614 (9% of original price) = 13,999.986 which is rounded to 14,000.00.
Therefore, the answer of 15,384.60 is correct.
Answer:
311.36
Step-by-step explanation:
For a geometric series sum of first n terms is 
if r is less than 1.
where a is the first term and r is the common ratio.
____________________________\
given
a = 108
r = 
n = 8
thus , sum of n term is
Thus sum of first 8 terms is 311.36
