Bug P has moved to +12 in 4 seconds, so is moving +3 units in each second.
.. x = 3t
Bug N has moved to -8 in 4 seconds, so is moving -2 units in each second.
.. y = -2t
_____
"per" means "divided by" (and vice versa), so -8 units per 4 seconds means
.. (-8 units)/(4 seconds) = -2 units/second . . . . . . . . reduce the fraction
When you multiply this fraction by a number of seconds, you cancel the "seconds" and the result is some number of units. For example,
.. (-2 units/second)*(4 second) = -8 units·second/second = -8 units
That is, speed multiplied by time gives distance.
In the equations above, we understand that the "3" means "3 units/second", and the "t" means "t seconds". Then when you multiply, the resulting x means "x units". The measures are usually left off and the equations are understood to give correct results when the variables have appropriate measures.
Yes, it's a polynomial it is also a trinomial, so your answer would be C.
Answer:
False
Step-by-step explanation:
6 miles / 30 quarts
Divide by 6
1 miles / 5 quarts
30 miles /15 quarts
Divide by 15
2 miles/1 quart
These are not the same so they are not proportional
