Your answer is D,
3 + d -3<3 - d -3 , you minus three from both sides.
Results :d<-d
Then, d+d<-d+d.
Which is, 2d/2<0/2.
Answer : d<0
Step-by-step explanation:
The given data is :
195, 194, 191, 190, 238, and 192
Mean = (sum of observations)/(total no. of observations)
So, the mean is the best measure. Also, w can find median as follows.
arranging in order : 190,191,192, 194, 195,238
Here, n = 6
Hence, this is the required solution
This is one half of a simultaneous equation. Without the other half, the values are theoretically unsolvable.
With that said, with trial and error you can work this out. I came out with an answer of x=1, y=12.
This is not a good practice. It's time consuming to solve simultaneous questions like this. Make sure you use the other half of the equation in the future.
I hope this helps!

Answer:
(-7,2)
Step-by-step explanation:
The point (7,-2) when reflected across the x-axis becomes (7, 2). When it is reflected across the y-axis it becomes (-7,2). You can find this because when a point is reflected across the x-axis, its y-coordinate changes its sign. The same is true when reflected across the y-axis. It's x coordinate changes its sign.
A double reflection across both axis changes the sign of each coordinate.
