8 <=u <=12
need at least 8, no more than 12
if you could have fractions of ppl it would be
8 <=u <13
It would be a rotation I believe
The answer is -5x + 4y = -20
Step-by-step explanation:
If two quantities x and y vary (change) together in such a manner that the ratio of their corresponding values remains constant, then x and y are said to be in direct proportion.
