Which shows the pre-image od quadrilateral w’x’y’z’ before the figure was rotated according to the rule (x,y) -> (-x,-y)?

Students were requested to answer a question at institution and to say what is most important for them to succeed. Of the many responses, one which that stood out was practice. Persons who commonly successful do not become successful by being born. They work hard and dedicate their lives to succeeding. If you want to reach your goals, keep this in mind! shown below some question and answer examples that you can certainly make use of to supercharge your knowledge and gain insight that will guide you to sustain your school studies.


Consider the following system with the solution (1,3)

Equation 1 of the system : 2x+y=5
Equation 2 of the system: x -2y =-5
Prove that replacing the first equation with the sum of that equation and a multiple of the other produces a system with the same solution
Posible answers : used multiplication property of equality to write a new equation
Used addition property of equality to write a new equation added equations 1 and 3


When a shape is rotated, it must be rotated through a center of rotation.

See attachment for the pre-image of W’X’Y’Z

From the attached graph, we have:

The rotation rule is given as:

When the rotation is reversed, the coordinates of the pre-image WXYZ are as follows:

The options are not given. So, I’ve added an attachment that illustrates the pre-image WXYZ

From the answer and question examples above, hopefully, they can help the student answer the question they had been looking for and remember of most things stated in the answer above. Then could certainly carry out some sharing in a group discussion and also study with the classmate relating to the topic, so another student also obtain some enlightenment and still keeps up the school learning.
