Answer:
The vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5). The graph of image and preimage is shown below.
Step-by-step explanation:
From the given figure it is noticed that the vertices of triangle ABC are A(0,0), B(1,5) and C(-4,5).
If a figure rotated at 180º about the origin, then
![P(x,y)\rightarrow P'(-x,-y)](https://tex.z-dn.net/?f=P%28x%2Cy%29%5Crightarrow%20P%27%28-x%2C-y%29)
The vertices of image are
![A(0,0)\rightarrow A'(0,0)](https://tex.z-dn.net/?f=A%280%2C0%29%5Crightarrow%20A%27%280%2C0%29)
![B(1,5)\rightarrow B'(-1,-5)](https://tex.z-dn.net/?f=B%281%2C5%29%5Crightarrow%20B%27%28-1%2C-5%29)
![C(-4,5)\rightarrow C'(4,-5)](https://tex.z-dn.net/?f=C%28-4%2C5%29%5Crightarrow%20C%27%284%2C-5%29)
Therefore the vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5).
The graph of image and preimage is shown below.
Answer:
20x + 22
Step-by-step explanation:
34- 4x + 12x -12 +12x
step 1: 34 - 12 = 22
now you have left: -4x + 12x +12x
step 2: 12x +12x = 24x
step 3: 24x - 4x = 20x
Now you will combine the two answers you got: 20x +22
Hope this helps :)
