You will have 19 in each bag and will have 3 left over.
62=2×31
82=2×41
so the answer is 2
5x + 2y = 7....multiply by -3
-2x + 6y = 9
----------------
-15x - 6y = -21 (result of multiplying by -3)
-2x + 6y = 9
---------------add
-17x = - 12
x = 12/17 or 0.7
5x + 2y = 7
5(12/17) + 2y = 7
60/17 + 2y = 7
2y = 7 - 60/17
2y = 119/17 - 60/17
2y = 59/17
y = 59/17 * 1/2
y = 59/34 or 1.7 when rounded <====
If you would like to know what was the temperature after the increase, you can calculate this using the following step:
the beginning temperature: -9
increased: 37
the temperature after the increase: -9 + 37 = 28oF
The temperature after the increase was 28oF.
Answer: y = 
<u>Step-by-step explanation:</u>
y = ax² ; where a represents the vertical stretch
a reflection across the x-axis is represented by making the a-value negative.
