What is the length of the segment joining the points at (4,5) and (6,-2) round to the nearest tenth if necessary

Segment xy is dilated through point m with a scale factor of 2. which segment shows the correct result of the dilation

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
