What is the ordered pair of x′ after point x (3, 4) is rotated 180°?

Answer : Rotation of a point through 180°, about the origin when a point X (3, 4) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position X' (-3, -4).

Answer with explanation:

Pre image= Coordinates of point X= (3,4)

When point ,(x,y) is rotated by an angle of 180°, then coordinates of image that is point (x,y) after rotation = (-x, -y)

⇒≡Coordinates of point X(3,4) after rotation by an angle of 180°=X'(-3,-4)

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
