Answer:
The coordinates are and
.
Step-by-step explanation:
First, we have to derive an expression for translation under the assumption that each point of XYZ experiments the same translation. Vectorially speaking, translation from X to X' is defined by:
(1)
Where is the vector translation.
If we know that and
, then the vector translation is:
Then, we determine the coordinates for Y' and Z':
The coordinates are and
.
Answer:
x=
Step-by-step explanation:
mutiply both sides of the equation by 6
12x-2n=3
move the bariable to the right hand side and change its sign
12x=3+2n
divide both sides
x=+1/6n
use commutative propert to reorder the terms
x= 1/6n +
and thats it, i hope this helps ya!
