I need help figuring out the coordinate planes of these points ASAP.

d1i1m1o1n [39]

<u>Given</u>:

The vertices of the quadrilateral WXYZ are W(2,4), X(4,2), Y(2,1) and Z(0,2)

The graph is rotated 90° about the origin.

We need to determine the coordinates of the quadrilateral W'X'Y'Z'

<u>Coordinates of the quadrilateral W'X'Y'Z':</u>

The rule to transform the coordinates 90° counter clockwise about the origin is given by

$(x, y) \implies(-y, x)$

Let us substitute the coordinates.

The coordinates of W' is given by

$W(2,4)\implies W'(-4,2)$

The coordinates of X' is given by

$X(4,2) \implies X'(-2,4)$

The coordinates of Y' is given by

$Y(2,1) \implies Y'(-1,2)$

The coordinates of Z' is given by

$Z(0,2) \implies Z'(-2,0)$

Therefore, the coordinates of the vertices W', X', Y' and Z' are (-4,2), (-2,4), (-1,2) and (-2,0) respectively.

Use words to explain how to multiply (33)(34).

Setler [38]

Answer:

The answer is 1122.

Step-by-step explanation:

First, multiply 34 by 3. That gives you 102.

Then multiply 34 by 3 again. But when you're writing this down in calculations, put a zero in the ones column then write your answer. (I'll show an example of what this looks like at the bottom.

Then, add your answers and you'll have your answer...
