Answer:
17/30
Step-by-step explanation:
2/5 + 1/6 = 17/30
Make them easier to add by making them have the same denominator.
2/5 = 12/30
1/6 = 5/30
12/30 + 5/30 = 17/30
Answer:
.
Step-by-step explanation:
The given point is K(-7,-2).
The mapping for 270 clockwise rotation about the origin is 
.
The image of K(-7,-2) after a 
clockwise rotation is (2,-7).
When (2,-7) is shifted 3 units down, then x-coordinate will remain the same but the y-coordinate will reduce by 3 units.
The image K(-7,-2) after 270 degrees clockwise rotation followed by a shift of 3 units down is .
Answer:
(- 396, 264 )
Step-by-step explanation:
Since the dilatation is centred at the origin, then multiply each of the coordinates of the point by the scale factor, that is
(- 9, 6 ) → ( (- 9 × 44 ), (6 × 44 ) ) = ( - 396, 264 )
