Option A is the correct answer, y = x + 2
y - 3 = x-1
If you bring the 3 to the R.H.S, it becomes y = x + 2
If you substitute the values,
3 = 1 + 2
3 = 3
Thus, e equation is correct
104 = 10,000 x 1.33 = 13,300
Respiratory on the first one
9,660/0.5m3=19.320kg/m^3
Get it from this equation m=pV
p is density ,V volume, m mass
Hope it helps ;)
