The point c (x,y) is in quadrant i. It is the vertex of a triangle. You reflect the triangle over the x-axis, then you dilate the triangle by the scale factor 2,Select an ordered pair that could be the coordinate of C" after the motion has been described

Answer:

[tex]C" = (2x,-2y)[/tex]

Step-by-step explanation:

Given

[tex]C = (x,y)[/tex]

First, reflect over x-axis

The transformation rule for reflection over the x-axis is:

[tex](x,y) =>(x,-y)[/tex]

So:

[tex]C = (x,y)[/tex] [tex]==>[/tex] [tex]C' = (x,-y)[/tex]

Next, dilate by 2

The transformation rule for dilation is: k(x,y)

Where

[tex]k = 2[/tex]

So:

[tex]C' = (x,-y)[/tex] [tex]==>[/tex] [tex]C" = 2 * (x,-y)[/tex]

[tex]C" = (2x,-2y)[/tex]
