<h3>Answer:  (12,3)</h3>

======================================================

Explanation:

R is located at (3,4). Move it 3 units to the left and 4 units down to have it move to (0,0). Call this point A. Apply the same translation rule to point B so that (2,-5) moves to (-1,-9). Let's call this point C

Now you'll use the rule (x,y) \to (-y,x) which rotates any point around the origin 90 degrees counterclockwise. So we're rotating C around A.

Point C has the coordinates (-1,-9). When you use the rotation rule (x,y) \to (-y,x) we get (-1,-9) \to (-(-9), -1) = (9, -1). We'll call this point D

Finally, undo the translation rule done at the start of the problem. So we'll go 3 units to the right and 4 units up to have point D move to point E = (12,3) which is exactly where point B' is located.

Check out the diagram below.

Answer: norm of reaction

Step-by-step explanation:

norm of a reaction which is the capacity of a genotype to produce different phenotypes in response to the environment. The group of phenotypic expressions under different environmental conditions. A organism can own all the genetic complements necessary to fully development. However, if there is no suitable nutricion, the development does not occur. The environment only changes the phenotypic characteristics within certain limits ruled by the genotype (norm of reaction). The genotype do not determine a phenotypes, but a amount of possible phenotypes, a norm of reaction. A certain phenotype will  materialize itself depending on the interaction of a certain genotype with the environment.

Answer: Choice D

-------------------------------------

Work Shown:

|2x - 6| < 4
-4 < 2x - 6 < 4
-4 + 6 < 2x - 6 + 6 < 4 + 6
2 < 2x < 10
2/2 < 2x/2 < 10/2
1 < x < 5

Plot open circles at x = 1 and x = 5 on the same number line
The shading will be in between the two open circles

That is why the answer is choice D
