Help me please translations hw

Answer 1

The locations of the vertices are shown below:

1. (- 5, 4), (- 4, 4), (- 5, 2)
2. (- 4, 1), (- 1, 2), (0, - 1), (- 2, - 5)
3. (2, 5), (3, 4), (1, 2)
4. (3, - 5), (- 2, - 3), (0, - 1)

What are the coordinates of the images resulting from a translation?

Herein we find four representations of polygons on Cartesian plane and we must determine the coordinates of the images generated by translation, a kind of rigid transformations. Translation is described by the following operation:

P'(x, y) = P(x, y) + T(x, y)

Where:

• P(x, y) - Original point
• P'(x, y) - Resulting point
• T(x, y) - Translation vector

Case 1 (K(x, y) = (3, - 3), X(x, y) = (4, - 3), R(x, y) = (3, - 5), T(x, y) = (- 8, 7))

K'(x, y) = (3, - 3) + (- 8, 7) = (- 5, 4)

X'(x, y) = (4, - 3) + (- 8, 7) = (- 4, 4)

R'(x, y) = (3, - 5) + (- 8, 7) = (- 5, 2)

Case 2 (E(x, y) = (0, 2), X(x, y) = (3, 3), V(x, y) = (4, 0), Z(x, y) = (2, - 4), T(x, y) = (- 4, - 1))

E'(x, y) = (0, 2) + (- 4, - 1) = (- 4, 1)

X'(x, y) = (3, 3) + (- 4, - 1) = (- 1, 2)

V'(x, y) = (4, 0) + (- 4, - 1) = (0, - 1)

Z'(x, y) = (2, - 4) + (- 4, - 1) = (- 2, - 5)

Case 3 (G(x, y) = (- 4, 5), J(x, y) = (- 3, 4), U(x, y) = (- 5, 2), T(x, y) = (6, 0))

G'(x, y) = (- 4, 5) + (6, 0) = (2, 5)

J'(x, y) = (- 3, 4) + (6, 0) = (3, 4)

U'(x, y) = (- 5, 2) + (6, 0) = (1, 2)

Case 4 (V(x, y) = (0, 0), Y(x, y) = (- 5, 2), F(x, y) = (- 3, 4), T(x, y) = (3, - 5))

V'(x, y) = (0, 0) + (3, - 5) = (3, - 5)

Y'(x, y) = (- 5, 2) + (3, - 5) = (- 2, - 3)

F'(x, y) = (- 3, 4) + (3, - 5) = (0, - 1)

Answer 2

Answer:

See attachments.

Step-by-step explanation:

A translation is a type of transformation that moves a figure left, right, up or down.  Every point on the original figure is translated (moved) by the same distance in the same direction.

• If a figure is to be moved left, subtract the number of units it is to be moved from the x-values.
• If a figure is to be moved right, add the number of units it is to be moved to the x-values.
• If a figure is to be moved up, add the number of units it is to be moved to the y-values.
• If a figure is to be moved down, subtract the number of units it is to be moved from the y-values.

Question 1

Coordinates of the given pre-image:

• K = (3, -3)
• R = (3, -5)
• X = (4, -3)

Given mapping rule:

$(x, y) \rightarrow (x-8, y+7)$

This tells us to subtract 8 from the x-values and add 7 to the y-values.

$\sf \implies K(3,-3) \rightarrow K'(3-8, -3+7)=K'(-5,4)$

$\sf \implies R(3,-5) \rightarrow R'(3-8, -5+7)=R'(-5,2)$

$\sf \implies X(4,-3) \rightarrow X'(4-8, -3+7)=X'(-4,4)$

Question 2

Coordinates of the given pre-image:

• E = (0, 1)
• X = (3, 3)
• V = (4, 0)
• Z = (2, -4)

Given mapping rule:

$(x, y) \rightarrow (x-4, y-1)$

This tells us to subtract 4 from the x-values and subtract 1 from the y-values.

$\sf \implies E(0,1) \rightarrow E'(0-4, 1-1)=E'(-4,0)$

$\sf \implies X(3,3) \rightarrow X'(3-4, 3-1)=X'(-1,2)$

$\sf \implies V(4,0) \rightarrow V'(4-4, 0-1)=V'(0,-1)$

$\sf \implies Z(2,-4) \rightarrow Z'(2-4, -4-1)=Z'(-2,-5)$

Question 3

Coordinates of the given pre-image:

• G = (-4, 5)
• J = (-3, 4)
• U = (-5, 2)

Given mapping rule:

$(x, y) \rightarrow (x+6, y)$

This tells us to add 6 to the x-values and the y-values remain unchanged.

$\sf \implies G(-4,5) \rightarrow G'(-4+6, 5)=G'(2,5)$

$\sf \implies J(-3,4) \rightarrow J'(-3+6, 4)=J'(3,4)$

$\sf \implies U(-5,2) \rightarrow U'(-5+6, 2)=U'(1,2)$

Question 4

Coordinates of the given pre-image:

• F = (-3, 4)
• V = (0, 0)
• Y = (-5, 2)

Given mapping rule:

$(x, y) \rightarrow (x+3, y-5)$

This tells us to add 3 to the x-values and subtract 5 from the y-values.

$\sf \implies F(-3,4) \rightarrow F'( -3+3, 4-5)=F'(0,-1)$

$\sf \implies V(0,0) \rightarrow V'( 0+3, 0-5)=V'(3,-5)$

$\sf \implies Y(-5,2) \rightarrow Y'( -5+3, 2-5)=Y'(-2,-3)$
