I thought of it as answering a regular equation and imagine it's equal signs but when your done solving you with have like ex x<5 and where ever the butt of the arrow is pointing is where the lines goes if there's ano equal sign below it then it is includive
<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by
![(x, y) \Rightarrow(-y, x)](https://tex.z-dn.net/?f=%28x%2C%20y%29%20%5CRightarrow%28-y%2C%20x%29)
Substituting the coordinates of the point C in the above formula, we get;
![(2, 1) \Rightarrow(-1, 2)](https://tex.z-dn.net/?f=%282%2C%201%29%20%5CRightarrow%28-1%2C%202%29)
Therefore, the coordinates of the point C' is (-1,2)
Answer:
10)
No. Since the garage is a square, the length and width are the same. And since the formula to find the area of a square is (length times width) l x w , that means that the square root of 121 would be the length and width of the garage. The square root of 121 is 11, concluding that the car that measures 13 feet long is too large.

7. its the square root of 49, which is the closest to 55.
hope this helps!
