Triangle GHJ with vertices G(-2, 4), H(3, 6), and J(3, -2) is dilated by a factor of 1/3 centered at the origin. What are the co

Grace [21]

Answer:

The coordinates of G' are $G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$ .

Step-by-step explanation:

From Linear Algebra, we define the dilation of point G by the following expression:

$G'(x,y) = O(x,y) + k\cdot [G(x,y)-O(x,y)]$ (1)

Where:

$O(x,y)$ - Center of dilation, dimensionless.

$k$ - Scale factor, dimensionless.

$G(x,y)$ - Coordinates of point G, dimensionless.

$G'(x,y)$ - Coordinates of point G', dimensionless.

If we know that $O(x,y) = (0,0)$ , $k = \frac{1}{3}$ , $G(x,y) = (-2,4)$ , then the point G' is:

$G'(x,y) = (0,0) + \frac{1}{3}\cdot [(-2,4)-(0,0)]$

$G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$

The coordinates of G' are $G'(x,y) = \left(-\frac{2}{3}, \frac{4}{3} \right)$ .

Answer:

1 -9/7n

Step-by-step explanation:

$\dfrac{1}{7}-3\left(\dfrac{3}{7}n-\dfrac{2}{7}\right)=\dfrac{1}{7}-\dfrac{3\cdot3}{7}n+\dfrac{3\cdot2}{7}=\dfrac{1}{7}+\dfrac{6}{7}-\dfrac{9}{7}n\\\\=\dfrac{1+6}{7}-\dfrac{9}{7}n=\boxed{1-\dfrac{9}{7}n}$
