Answer:
During the 1960's the disclosure of enormous gas and oil fields in Alaska accelerated the change of most coal framework to other petroleum products. During this period Usibelli Coal Mine bought the Suntrana mine and the mining activities in the Matanuska coal fields stopped activity.
Answer:
1. (x-4), (y+4)
2. In a transformation, the equation shows how much the original coordinate moves. In the equation above, the orignal coordinate would move to the left 4 places, and then up 4 places. This particular transformation is called a translation, as the shape is the same but only in a different spot.
3. Quadrilateral
4. The transformed polygon has the apostrophes after each letter, which means it is "prime" or not the original.
Explanation:
1. To write the equation, look at how the shape shifts. If the x coordinate moved 4 spaces to the left, then that means the equation is -4. Do the same for the y-coordinate, except keep in mind it is up and down instead of left or right.
2. The answer is self-explanatory.
3. A quadrilateral has 4 sides, and this can be applied to more specific shapes, such as a square or rectangle. Because this shape has no distinctive features, it is safest to call it a quadrilateral.
4. The answer is self-explanatory.
