9 I believe is the answer is to th question. Not sure
Answer:
10
Step-by-step explanation:
The answer would be the first choice. When you reflect a shape across the x-axis, the y coordinates of every points/vertices become of the opposite of what they usually were.
For example, the y coordinate in (1, -5) {{-5 being the y coordinate) once reflected upon the x axis would be (1, 5).
On the other hand, if the y coordinate were positive it would become negative.
Answer:
1.8
Step-by-step explanation:
(2x90):100
180:100 = 1.8
The best thing to do is to divide 1440 by 240, which will allow you to find a unit rate (which will be the length of time that the journey takes)
1440/240= 6.
Therefore, the journey takes 6 hours
Hope this helps :)
