$Solution, \frac{-4r}{4}+\frac{5r}{3}=\frac{2r}{3}$

$Steps:$

$\frac{-4r}{4}+\frac{5r}{3}$

$\frac{-4r}{4},\\\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b},\\-\frac{4r}{4},\\\mathrm{Divide\:the\:numbers:}\:\frac{4}{4}=1,\\-r,\\-r+\frac{5r}{3}$

$\mathrm{Convert\:element\:to\:fraction}:\quad \:r=\frac{r3}{3},\\\frac{5r}{3}-\frac{r\cdot \:3}{3}$

$\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c},\\\frac{5r-r\cdot \:3}{3}$

$5r-r\cdot \:3,\\\mathrm{Add\:similar\:elements:}\:5r-3r=2r,\\\frac{2r}{3}$

$The\:Correct\:Answer\:Is\:\frac{2r}{3}$

$Hope\:This\:Helps!!!$

For figure ABCDEF shown here, identify the image after a reflection across the line connecting the

Angelina_Jolie [31]

Answer:

The image will be DCBAFE

Step-by-step explanation:

A polygon with six sides is called a hexagon

In this question first identify the midpoints of BC and EF using perpendicular bisector.

This should be followed by joining the two midpoints with a straight edge to draw the mirror line.

The points above the mirror line F,A and B will be reflected below the mirror line.The points below the mirror line C,D and E will be reflected above the mirror line.

The image will be DCBAFE
