30 (miles) times 4 (hours) equals to 120 miles. 400 miles minus 120 miles equals 280 miles (distance the other car has driven). 280 divided by 4 (because we want to find the speed for only one hour) equals 70 miles.
The average speed of the other car is 70 mph
810/10.8 = 75 ...so as the answer
Answer:
(-5, 3)
(-2, 6)
(-4, -2)
Explanation:
To translate 5 units up means to add 5 to the y value since the y-axis dictates the vertical positioning of a coordinate. However, the x-values remain unchanged.
So all the y values are -2, 1, and -7. Add 5 to all of these.
-2 + 5 = 3
1 + 5 = 6
-7 + 5 = -2
Then re-pair them with their x-values like so:
(-5, 3)
(-2, 1)
(-4, -2)

To find the median, you list the numbers in increasing order.
5, 5, 7, 10, 13.
Then you take the middle number. Every number has a pair except for seven in the middle, and the median is 7. Hope it helps!
