Answer:

y=11

Step-by-step explanation:

To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.

To Check your answer:

Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.

Parallelogram JKLM is shown on the coordinate plane below:
Harlamova29_29 [7]

if JKLM is rotated 270° clockwise around the origin, the new vertices is at:

J'(-2, -6), K'(-6, -4), L'(-3, -3) and M'(1, -5)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rotation is the movement of a figure about a fixed point. If a point A(x, y) is rotated 270° clockwise around the origin, the new point is A'(-y, x).

The vertices of the parallelogram is at J(-6, 2), K(-4, 6), L(-3, 3) and M(-5, -1). Therefore if JKLM is rotated 270° clockwise around the origin, the new vertices is at:

J'(-2, -6), K'(-6, -4), L'(-3, -3) and M'(1, -5)

Therefore K′(−6, −4); L′(−3, −3) is the correct option
