Answer:
The vertex Q' is at (4,5)
Step-by-step explanation:
Given:
Quadrilateral PQRS undergoes a transformation to form a quadrilateral P'Q'R'S' such that the vertex point P(-5,-3) is transformed to P'(5,3).
Vertex point Q(-4,-5)
To find vertex Q'.
Solution:
Form the given transformation occuring the statement in standard form can be given as:
The above transformation signifies the point reflection in the origin.
For the point P, the statement is:
So, for point Q, the transformation would be:
Since two negatives multiply to give a positive, so, we have:
Answer : and
Greatest common factor of
If we are able to factor out from each option then that would be our answer.
Lets check with each options
(a), we cannot take out 5.
(b), We can take out common factor and it can be written as
(c) , we cannot take out n^2 because we have only 'n'
(d) , We can take out common factor and it can be written as
(e) , we cannot take out 5 because we have 24
So answer is (b) and (d)
