Find the image of A(6, -4) after it is reflected over the line y = - 2, then reflected over the line x = 1. (-4, 6) (-4, 0) (-4,

olchik [2.2K]

Answer:(-4,0)

Step-by-step explanation:

Given

Point A (6,-4)

Reflection of Point A about line y=-2 is

A' (6,0)

If any Point is reflected about any line y=constant then its x coordinate remains same

Now reflection of Point A' about x=1 is

A'' (-4,0)

If any point is reflected about line x=constant then its y coordinate remains same

Consider the line y=1 x -1 and the point P=(2,0).

Montano1993 [528]

Answer:

Step-by-step explanation:

d(x)=√((x-2)2+(y-0)²)

=√((x-2)²+y²)

=√((x-2)²+(x-1)²)

=√(x²-4x+4+x²-2x+1)

=√(2x²-6x+5)

D=d²(x)=2x²-6x+5

$b.\\\frac{dD}{dx}=4x-6\\\frac{dD}{dx}=0,gives \\4x-6=0\\x=\frac{3}{2}\\\frac{d^2D}{dx^2}=4 >0 at x=\frac{3}{2}\\so~D~or~d^2~or~d~is~minimum~at~x=\frac{3}{2}\\so~y=1(\frac{3}{2} )-1=1/2=0.5\\so~nearest~point~is~(1.5,0.5)$
