No. It's rational. The solutions are +10 and -10.
Answer:
No
Step-by-step explanation:
If it were proportional, then the price for each apple would double.
(15 + 8d) (- 5) - 24d + d
- 75 - 40d - 24d + d
- 75 - 63d
All you have to do here is subtract the 3/8 on the left from the 17/8 on the right and you get 14/8 which reduces to 7/4 which is 1 3/4.
I think x = 46 and y = 18. 8y - 102 is vertical to 2y + 6 so you would make them equal each other. You would solve and end up with 18. To find 3x, you would see that 8y - 102 is supplementary to it and they would have to equal 180. If you substitute 18 into 8y - 102 it would be 42. 180 - 42 is 138 so you would divide and do 138/3 which would leave you with 46.
