Line segment XY has endpoints at (1, −3) and (5, −4). The segment reflects over the x-axis. Then, it undergoes a translation 3 u

morpeh [17]

Answer: The new endpoints are (4,3) and (8,4)

Step by step:

First, reflext around the x axis. This really means flipping the sign of the y coordinates:

$(1,-3)\rightarrow(1,3)\\(5,-4)\rightarrow(5,4)\\$

Then apply horizontal translation by +3 units. A horizontal translation means adding units to the x coordinates:

$(1,3)\rightarrow(4,3)\\(5,4)\rightarrow(8,4)\\$

Quadrilateral QRST is a rectangle. RT = 5x + 1 and QS = 6x – 3. Find QS.

Kaylis [27]

Answer:

Step-by-step explanation:

RT and QS are diagonals of the rectangle and are equal in length.

5x + 1 = 6x - 3

-x = -4

x = 4

So QS = 6(4) - 3

= 21.
