What is the image of (−8,−8) after a dilation by a scale factor of 1/2 centered at the origin?

(-4,-4)

Step-by-step explanation:

Since this is centered at (0,0), we have to multiply the x and the y coordinates by the scale factor.

-8 × 1/2 = -4

he will have 3 beads left over

Step-by-step explanation:

29 + 23 + 31 = 83 beads used for a set of 3 bracelets of the 3 designs

750/83 = the no. of sets of 3 bracelets of the 3 designs

750/83 = 9 sets with a remainder of 3

So, he will have 3 beads left over
