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

Hello, I'm trying to solve 6x + y = 4, x - 4y = 19. I have found the y but I cant seem to find the x. Plz help and we cant use d

Answer:

$x=\frac{7}{5}$

$y=-\frac{22}{5}$

Step-by-step explanation:

Given:

The given expressions are.

$6x+y=4$

$x-4y=19$

We need to find x and y values.

Solution:

Equation 1⇒ $6x+y=4$

Equation 2⇒ $x-4y=19$

First solve the equation 1 for y.

$6x+y=4$

$y = 4-6x$ --------(3)

Substitute $y = 4-6x$ in equation 2.

$x-4(4-6x)=19$

Simplify.

$x-(4\times 4 - 4\times 6x)=19$

$x-(16-24x)=19$

$x-16+24x=19$

Add 16 both side of the equation.

$25x-16+16=19+16$

$25x=35$

$x=\frac{35}{25}$

Divide Numerator and denominator by 5.

$x=\frac{7}{5}$

Substitute x value in equation 3 and simplify.

$y=4-6(\frac{7}{5})$

$y=4-\frac{6\times 7}{5}$

$y=4-\frac{42}{5}$

$y=\frac{5\times 4-42}{5}$

$y=\frac{20-42}{5}$

$y=-\frac{22}{5}$ .

Therefore, the value of $x=\frac{7}{5}$ and $y=-\frac{22}{5}$ .
