Here is a list of numbers:
-20, -20, 2, 7, -14, -4, -17, 13, 7
State the median.

-4

Step-by-step explanation:

arranging in ascending order

-20,-20,-17,-14,-4,2,7,7,13

number of terms=9

middle term= (n+1)/2=(9+1)/2=5th=-4

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
