Draw a line from point Q to point A. Then draw another line segment from point Q to point A'. These lines are marked in red in the attached image (figure 1). Notice we have a 90 degree angle form. To go from A to A', we rotate 90 degrees counterclockwise (green angle in figure 2). Or we can rotate 270 degrees clockwise (gray angle in figure 2).

So that's why the two answers are:

choice B) 90 degrees counterclockwise

choice D) 270 degress clockwise

Side Note: the other points (B, C, and D) will follow a similar rotation path compared to point A. Either rotate those preimage points 90 degrees counterclockwise or 270 degrees clockwise so they match with their respective image points. All rotations are done around point Q.

Nina and her friends have $40 to

DochEvi [55]

Answer:

2s+5p=40

Step-by-step explanation:

s=sodas

If f(x) = 3x+2 then what is f(2)+1

Vilka [71]

Answer: 9

Solving Steps:
f(x) = 3x + 2
f(2) = 3*2 + 2
f(2) = 6 + 2
f(2) = 8
f(2) + 1
8 + 1 = 9

State the Multiplicative identity property of one using the variable b.

KengaRu [80]

For a property with such a long name, it's really a simple math law. The multiplicative identity property states that any time you multiply a number by 1, the result, or product, is that original number. To write out this property using variables, we can say that n * 1 = n.
