What transformations were applied to abcd to obtain a’b’c’d’?

B) 90° counterclockwise, translation 3 units to the left.

Step-by-step explanation: Given coordinates of figure ABCD are:

A (1,5).

B (1,9)

C ( 5,9)

D (5,5)

Coordinates of transformed image A'B'C'D' are :

A' (-8,1)

B' (-12,1)

C' (-12,5)

D' (-8,5).

We need to explain rule of transformation:

Let us compare coordinates of A and A'.

A (1,5)  ---> A' (-8,1)

We can see that (x,y) > (y,-x) > (y,-x-3) rule is being applied there.

So, according to (x,y) > (y,-x) rule, it's Rotation of 90 degrees counterclockwise.

And (y,-x) > (y,-x-3) is translation 3 units to the left.

Therefore,

18a

step-by-step explanation:

simply because it is. it's the highest common factor

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
