Answer:
35
Step-by-step explanation:
x-18=y
y*-3=-51
y=17
x-18=17
17+18=x
x=35
OMG I HAD THIS EXACT HOMEWORK LAST YEAR CREEPYYYYY!!!!

Answer:
Step-by-step explanation:
If you draw a line from the origin (0,0) to L ( the original point ) and a different line from the origin to the image L' you can see the angle of rotation as being
90 degrees and that the rotation is clockwise.
the rule is (x, y) become ( y, -x)
Answer:
7^2 ( little 2 in the corner)
For a better understanding of the explanation provided here, please find the diagrams in the two files that have been attached.
As can be clearly seen from the diagram, PR and QS are the diameters of the circle and they intersect each other at the centre, O of the circle.
The angle these diameters make at the point of intersection O is 90 degrees.
If Margot joins the points P,Q,R and S which are on the circumference of the circle, then we will get a square with sides PQ, QR, RS and SP as shown in the second diagram.
Thus, the correct option is Option A.
