Answer= c
In this case you've got to place the vector from the origin, so you have to get the difference from both points (x2-x1) and (y2-y1)
So you get that the vector from the origin is (18,-7)
Know you know the vector v is three times the vector u, so you multiply three times the vertex, but remember the vector v goes int he opposite direction, so the vector v from origin the the terminal point is (-54, 21)
Step-by-step explanation:
On the verge of troll, this question is.
"Two" : 2
"minus": -
"y" : y
2-y
<span>2(x - 5) + 7 = x + 8
Use distributed property
2x - 10 + 7 = x + 8
Add 7 to -10
2x - 3 = x + 8
Subtract x from both sides
x - 3 = 8
Add 3 to both sides
Final Answer: x=11</span>
Vertex position is fixed when it is the center of rotation but changes when the origin is the center of rotation.
