What is the image of (-9, -1) after a dilation by a scale factor of 2 centered at the
origin?

(- 18, - 2 )

Step-by-step explanation:

Since the dilatation is centred at the origin then multiply each of the original coordinates by the scale factor for image, that is

(- 9, - 1 ) → (2 × - 9, 2 × - 1 ) → (- 18, - 2 )

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

the first option is the answer.
