Answer:
- <u><em>a reflection of the line segment across the y-axis </em></u>
Explanation:
The transformations of the end points are:
Preimage Image
The means that, for every end point, the x-coordinate changes the sign and the y-coordinate remains unchanged.
That rule is:
- (x, y) → (- x, y): this is<em> a reflection across the y-axis</em>.
Keeping the y-coordinate and changing the sign of the x-coordinate is a reflection across the y -axis. It is like a mirror image, where the mirror is placed along the y-axis. The figure keeps the same distance from the y-axis (the mirror) but changes sides, which is represented by the change of x to - x, while the altitude (the y-coordinate) keeps unchanged.
First, boiling is the change of state from a liquid to a gas. Second, boiling of a pure substance occurs at a particular constant temperature called boiling point.
First, the change of state from a gas to a liquid is called condensation. Second, a pure substance condenses at a temperature equal to its boiling point.
Hope this helps you!
Answer:
The universe is comprised of more than 75% of materials that are not visible and are often considered to be the dark matter. These are the baryonic matter that is formed due to the accumulation of protons, neutrons as well as electrons. They can be baryonic or non-baryonic type of matter. These dark matters are the substance that interconnects mostly by gravity along with some visible matter such as the stars and planets. These matters do not reflect light and they attract other matters, forming the major mass of the entire universe.
Most of China’s ancient civilizations are hard to find mainly because of the harsh land scapes around mountains. And other areas.
