You are a kite sailing across the ocean. The table gives your height at different times.
A. How many feet do you move each second?
Answer: From the given table information, we clearly see that after every second the kite moves 2 feet
B. What is your speed? Give the units.
Answer: We know that :
Therefore, the speed of the kite is 2 feet per second
C. Is your velocity positive or negative?
Answer: The velocity is positive, because the height of the kite goes on increasing direction
D. What is your velocity? Give the units.
Answer: Here the velocity of kite is:
feet per second
Answer:
B
Step-by-step explanation:
Our system of equations is:
3x + y = 23
8x + 2y = 23
If we want to use substitution, that means that we essentially want to manipulate one of the two equations so that one variable (like y) is written in terms of the other (like x), and then substitute that expression into the second equation so that we have one variable and one equation and we can easily solve from there.
So the first thing to be done is to write one of the variables in terms of the other. It would be easiest to do it with the first equation and write y in terms of x - in other words, "solve the first equation for y".
The answer is B.
