I would say 3/10 because 6 and 20 can both be divided by 2 so 6/2 is 3 and 20/2 is 10 and they cant be reduced and farther so 3/10 would be my answer
2x^2 - 6xy + 5xy - 15y^2.
Which simplifies to:
2x^2 - xy - 15y^2.
The Correct statements are :
- The rate of change is not constant
- The relationship is non linear
- Independent variable is Age
- Dependent variable is selling price
- It is a negative relationship

1: 2x+y=3
5x-2y=12
2: Multiply the first equation by 2
(2) (2x+y=3) => 4x+2y=6
3: Add
4x+2y=6
+ 5x-2y=12
______________
9x=18 The y's cancel out
9x/9=18/9 The 9's cancel out
x=2
4: Plug (x=2) back into either equation but, I'm going to do the first one. It's easier.
2(2)+y=3
4+y=3
4-4+y=3-4 The 4's cancel out
y=-1
Answer: (12,-1)
If you plug (x) and (y) back in it will equal 3 for the first and 12 for the second.
