Answer: OPTION B.
Step-by-step explanation:
By definition, reflection is a kind of transformation in which the lengths do not change.
As you can see in the figure, the length of PR is 8 units. Then, keeping on mind the definition, when the triangle PQR was reflected across the y-axis, the triangle P'Q'R' obtained has the same lenghts as the triangle PQR.
Therefore, you can conclude that the lenght P'R' would be: 8 units.
(4,3) is a solution for y=3x-9 but not y=1/2+1.
I actually did this problem today for edge , I included a picture that I used to understand how to do this problem the answer is 1%.
84 kilometers ... 1 hour
7 kilometers ... x hours = ?
If you would like to know how long does the pigeon take to fly 7 kilometers, you can calculate this using the following steps:
84 * x = 1 * 7
84 * x = 7 /84
x = 7/84
x = 1/12 hour
Result: A pigeon can fly 7 kilometers in 1/12 hour.
