Answer:
<em>Liz hiked </em><em>0.16 miles</em><em> by herself.</em>
Step-by-step explanation:
Liz is hiking a trail that is 0.8 miles long. So the total length of her hiking is 0.8 miles.
Liz hiked the first 2 tenths of the distance by herself i.e she hiked th of the total distance.
So, the distance that she covered by herself is,
miles
Therefore, Liz hiked 0.16 miles by herself.

The x-coordinates of will be the negation of the x-coordinates of
The line segment from S to the y-axis equals the line segment from S' to the y-axis. Similarly, the line segment from T to the y-axis equals the line segment from T' to the y-axis

In order to solve this question, I will make the following assumptions.
Assume that the coordinates of are
Refer to attachment for illustrations
<u>(1) Reflect </u><u> over y-axis and describe the transformation</u>
To reflect across the y-axis, the following rule must be followed
This means that:
<u>The description of the </u><u>transformation </u><u>is as follows:</u>
Notice that the signs of the x-coordinates and
of both triangles are different.
In other words, if the x-coordinate of one is positive, then the other will have a negative x-coordinate; and vice versa.
<u>(2) Compare the segments and the line of reflection</u>
To reflect across the y-axis means that the reflecting line is the y-axis, itself.
The distance between a point to the y-axis is the absolute value of the x-coordinate.
So, the distance between S and the y-axis is:
The distance between S' and the y-axis is:
We can conclude that the two line segments are equal.
This is the same for other point T and T' because of the formula used above.
<u>From T and T' to the y-axis is:</u>
