Answer:
(12,0), (3, -1) (0,-4/3)
Step-by-step explanation:
To do this problem, you have to plug in the x and y values. For example, the first one would be 12-9(0)=12, and so on.
To solve this question, we simply need to subtract the two numbers.
We'll start by changing these into improper fractions to simplify things for now.
Now, we need to make these fractions share a common denominator. We'll do this by multiplying the second fraction by . Keep in mind that whatever is done to the denominator must also be done to the numerator.
Finally, subtract the numerators and keep the denominators.
We can simplify this fraction by dividing both the numerator and the denominator by .

1) Speed is measured in distance units divided by time units, such as miles per hour. Here, you're given the number of miles traveled and the number of hours it takes, so you can figure tha average speed to be
... speed (or "rate of change") = distance/time = 165 mi/(3 h) = 55 mi/h
2) "speed at the moment" 1.5 hours into the flight means ...
... d. an instantaneous rate of change at 1.5
3) To keep their average speed on target, the dragons must travel at higher than their average speed for a while.
Eleven, three hundredths, and seven thousandths.
