The answer is 14 you just have to substitute x with the given number and finish the equation
Answer:
3Y - 4X - 4
Step-by-step explanation:
your answer is 15.8 (im pretty sure)
Answer:
D: (-1,2)
Step-by-step explanation:
The X coordinate is between 2 and -4. There is a difference of 6, so you should do -4 + (6/2) = -1.
so the X coordinate is -1
The y coordinate is between 0 and 4. There is a difference of 4, so you should do 0 + (4/2) = 2.
so the y coordinate is 2
This results in the centre being (-1,2)
To find the rate (or speed) of an object you use the equation
Rate = Distance x Time or
d = rt So, just fill in the equation with the first set of numbers.
64 = r(1.7) Then divide.
r ≈ 37.65
Then, find the second speed.
d = rt
80 = r(1.9) And divide.
r ≈ 42. 11
Since you need to find the average speed just find the average of the two speeds. So
(42.11 + 37.65) / 2
79.76 / 2
39.88
So the average speed of the train was about 39.9 miles per hour.
