Answer:
Option b (1/2,1/3)
Step-by-step explanation:
we have
2x-3y=0 ------> equation A
4x+6y=4 -----> equation B
Solve the system by elimination
Multiply equation A by 2 both sides
2(2x-3y)=2(0)
4x-6y=0 ------> equation C
Adds eqution B and equation C
4x+6y=4
4x-6y=0
-------------
4x+4x=4+0
8x=4
x=1/2
Find the value of y
2x-3y=0
2(1/2)-3y=0
1-3y=0
3y=1
y=1/3
the solution is the point (1/2,1/3)
That is 12000 sooo that is the answer
Answer:

Step-by-step explanation:
Set up the equation:
Since C(t) gives the number of cars purchased in the t-th year after 1998, then make the number of cars equal to 15 000 and solve for t - the year:
20t^2 = 15000
t^2 = 750
t = 
The year will be simply 1998 + 5 \sqrt{30}
