Danielle wants to translate triangle XYZ so that vertex Y is moved from coordinates (-
ira [324]

Answer:

We need to use the mapping U'(x,y) = (x+4,y-5) to find the new coordinates of X and Y.

Step-by-step explanation:

Vectorially speaking, we must look for the defintion of the translation operation such that vertex Y becomes vertex Y', which is represented by:

T(x,y) = Y'(x,y) - Y(x,y) (1)

Where T(x,y) is the translation vector.

If we know that Y(x,y) = (-4,2) and Y'(x,y) = (0,-3), then the translation vector is:

T(x,y) = (0,-3)-(-4,2)

T(x,y) = (4, -5)

If U(x,y) = (x,y), T(x,y) = (4, -5) and U'(x,y) is the translated vector, then we obtain the following definition:

U'(x,y) = U(x,y) +T(x,y) (2)

U'(x,y) = (x,y) + (4,-5)

U'(x,y) = (x+4,y-5)

The correct answer is B.

the area of a rectangle is 256.5 meters squared if the length is 18 meters what is the perimeter of the rectangle
PolarNik [594]
You would do 256.5/18 to get the other side which is 14.25, then you add 18 and 14.25 getting 32.25, now multiply that by 2 because there are 2 of each length sides, and you get 64.5 meters as the perimeter
