(7^8×7^3×7^4)/(7^9×7^5)=(7^(8+3+4))/(7^(9+5))=(7^15)/(7^14)=7^1=7
The answer is 7.
20x + 5y = 15
-20x -20x
5y = -20x + 15
/5 /5 /5
y = -4x + 3
I thinks it’s -x-4 I’m not sure
A square rotated about its center by 360º maps onto itself at 4 different angles of rotation. You can reflect a square onto itself across 4 different lines of reflection.
<h3>What is the rotation Transformation?</h3>
A rotation is a transformation in which the object is rotated about a fixed point. The direction of rotation can be clockwise or anticlockwise.
A square is a geometric figure which has all its four sides equal and all its interior angles are right angles (90°) .
Therefore, it can be rotated about its center by (360°).
It maps onto itself at 4 different angles of rotation (at every 90°).
Thus, we can reflect a square onto itself across 4 different lines of reflection (2 across the non-parallel sides and 2 across the vertices of the square).
Thus, we can conclude that A square rotated about its center by 360º maps onto itself at 4 different angles of rotation. You can reflect a square onto itself across 4 different lines of reflection.
