Rotation of 90 degrees counter clockwise of point A (7, 4).
Quadrant of given point: 1
Coordinates after the switch: 4, 7
Quadrant after rotation:
New coordinates after rotation:
Rotation of 180 degrees of point B at (-8, -2).
Quadrant of given point: 3
Quadrant after rotation: 1
New coordinates after rotation: 8, 2
Rotation of 270 degrees clockwise around the origin of point C at (9, -5).
Quadrant of given point: 4
Coordinates after the switch: 5, 9
Quadrant after rotation: 1
New coordinates after rotation: 5. 9
Rotation of 90 degrees clockwise around the origin of point D at (-6, -11).
Quadrant of given point: 3
Coordinates after the switch: 11, 6
Quadrant after the rotation: 2
New coordinates after rotation: -11, 6
9514 1404 393
Answer:
A'(-4, 7) . . . . ending in quadrant 2
check switched coordinates for C', D'
Step-by-step explanation:
The transformations accomplished by rotations are ...
(x, y) ⇒ (-y, x) . . . . . 90° CCW or 270° CW
(x, y) ⇒ (y, -x) . . . . . 90° CW or 270° CCW
(x, y) ⇒ (-x, -y) . . . . 180° (either direction)
You notice that coordinates are switched and one is negated in each of these transformations. I assume that your line "Coordinates after the switch" is intended to lead you through that first step, then "New coordinates after rotation" is intended to be the same set of coordinates with the appropriate sign change.
__
1. A(7, 4) 90° CCW ⇒ (4, 7) ⇒ A'(-4, 7) . . . . ending in quadrant 2
2. B(-8, -1) 180° ⇒ B'(8, 2) . . . . ending in quadrant 1 (correct)
3. C(9, -5) 270° CW ⇒ (-5, 9)* ⇒ C'(5, 9) . . . . ending in quadrant 1
4. D(-6, -11) 90° CW ⇒ (-11, -6)* ⇒ D'(-11, 6) . . . . ending in quadrant 2
_____
* I would leave the original signs on the "coordinates after the switch". Here, you have dropped the signs. I don't know what you've been taught, but that's not how I would do it, as you can see above.

Is 8,397 divisible by 9? If it is, write the number as the product of 9 and another factor. If not, explain.
Explain why 186,426 is divisible by both 3 and 9.
Answer:
No , because when we are adding it we don't get the number that's divisible by 3Yes ,it is divisible by 9 .We can do this by adding all the numbers 3+9+7=27Yes it is divisible by both 3 and 9 ,because when we are adding we get 1+8+6+4+2+6=27.And 27 is divisible in both the tables Please mark me as the Brainliest!!if the answer helped youUse the algebra tiles tool to model the equation

True or False?
The output values are the x-coordinates.
Answer:
The answer is false because if you have a set of ordered pairs, you can find the domain by listing all of the input values, which are the x-coordinates. And to find the range, list all of the output values, which are the y-coordinates. Hope this helps!! :))
