Answer:

The answer is rotation 270° about the origin

Step-by-step explanation:

If (x , y) is a point in xy-coordinates

If the point rotate about the origin ⇒ (The positive direction is anti-clockwise)

1- 90°

  Its image is (-y , x)

2- 180°

   Its image is (-x , -y)

3- 270°

   Its image is (y , -x)

If we assume A is (1 , 7)

1- ⇒ (-7 , 1) ⇒ rotation 90° about the origin

2- ⇒ (-1 , -7) ⇒ rotation 180° about the origin

3- ⇒ (7 , -1) ⇒ rotation 270° about the origin

∵ x-coordinate of point A small and +ve and y-coordinate large and +ve

∵ x-coordinate of point A' large and +ve and y-coordinate small and -ve

∴ The answer is rotation 270° about the origin

∴ The answer is rotation 270° about the origin

Answer:

<h2>A rotation of 90° about the origin.</h2>

Step-by-step explanation:

If you observe carefuly, notice that point A is next to y-axis, at the right side of the axis. Now observe that A' is right next to x-axis, at the right side if you put the North above the x-axis.

This transformation can be achieved by rotating around the origin 90°, a better way to deduct that is drawing a vertical line intercepting point A, and drawing a horizontal line intercepting point A'. You will notice that these lines are perpendicular each other.

Therefore, the right answer here is the first choice: A rotation of 90° about the origin.

What is the value of x in the equation-2/5x-2=18
Flura [38]
First we have to isolate the varible

-2/5x-2=18
        +2   +2

-2/5x=20

then divide both sides by -2/5 to get x completely by itself

-2/5x=20
-------  ---
-2/5     -2/5

x=-50

i hope i've helped!

Which properties justify the steps taken to solve the system?
Nutka1998 [239]

Answer:

X=-1

Y=1

Step-by-step explanation:

6x-12y

-18

) 6x + 4y

-

-2

Subtract the two equations

6x - 12y - (6x + 4y) = -18 - (-2)

Determine the sign

6x- 12y - 6x- 4y

=-18 + 2

Simplify

-12y

- Ay

=-18 + 2

Solve the equation

Substitute

6×+4

-2

Solve the equation

5 4/8 + 1 3/8 =<br> 1. 33/8<br> 2. 55/8<br> 3. 6 7/16
Dovator [93]

Answer: 2. 55/8

Step-by-step explanation: Add the whole numbers first (5+1 = 6), then add the fractions (4/8 + 3/8 = 7/8). Now we have 6 7/8 and since they want the answer in fraction form we will multiply the 6 and the 8 (6x8=48) and then add the 7 to the 48 (7+48 =55) and we leave our answer over the denominator which is 8. This leaves us with the final answer of 55/8
