Answer:
1 unit
Step-by-step explanation:
If point J is the midpoint of segment FG with endpoints F(1,4) and G(5,12), then its coordinates are
If point K is the midpoint of segment GH with endpoints G(5,12) and H(-1,4), then its coordinates are
The measure of JK is
Y = -1 is a horizontal line going through "-1" on the y axis
Note that the point (1,2) is exactly 3 units of distance above the line y = -1
When we reflect across this line, the point (1,2) will just move straight down to exactly 3 units of space below the line y = -1. Since we are not shifting left or right, the x coordinate of our original point will not change. The y coordinate of our original point will now need to be reduced by 6(3 units down to get to the line of reflection and then 3 more down to get to the image location)
The coordinates of the image point will be (1, -4)
Now we need to do the same process with (1, -4) being reflected across y=1
Note (1,-4) is 5 units of distance below the line y = 1 , so we need to reflect the point upward so that the image point is located exactly 5 units of distance above the line y = 1 Again, the x coordinate does not change, and our final image coordinates are (1, 6)
I guess more simply stated, if you're just looking for the number in the green box it would be " 1 " .. Reflecting points across horizontal lines only result in changes of the "y" coordinate since there is no shift left or right.
Answer:
20=5*-3+x or 20=-15+x or 35=x
48－4=44,in the left
6×7=42,in the right
44＞42,so ＞ is the answer
The median is nine (9). You add each number up, and then you divide by the amount of numbers you have.
The mean is 9.83 according to my calculations.
