Which rule describes the composition of transformations
that maps ajkl to aj"k"l"?
r0. 9000 to, -2(x, v)
t0, -2 ro, 900(x, y)
r0, 900 0 t-2, olx, y)
t-2,00 ro, 900(x, y)

The rule is R(o , 90°) and T (x - 2 , y)

Step-by-step explanation:

* Lets explain how to solve the problem

- If point (x , y) rotated about the origin by angle 90°  then its image

 is (-y , x)  ⇒ (90° means anticlockwise)

- If the point (x , y) translated horizontally to the left by h units  then

 its image is (x - h , y)

- In the figure Δ LJK has vertices L (2 , -2) , J (2 , -4) , K (5 , -4)

- If Δ LJK rotates 90° (anticlockwise) around the origin, then

 change the sign of y-coordinates of each vertex and switch x and y

 coordinates of each vertex

∴ The image of point L is L' = (2 , 2)

∴ The image of point J is J' = (4 , 2)

∴ The image of point K is K' = (4 , 5)

∵ The vertices of Δ L"J"K" are

  L" = (0 , 2)

  J" = (2 , 2)

  K" = (2 , 5)

- By comparing the vertices of Δ L'J'K' and Δ L"J"K", we will find

 each x-coordinate of Δ L'J'K' subtracted by 2 to give the vertices

 of Δ L"J"K"

∴ Δ L'J'K' is translated to the left by 2 units

∴ Δ LJK Rotates around the origin by 90° anticlockwise and translates

  2 units to the left

* The rule is R(O , 90°) and T (x - 2 , y)

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
