Round the number 6,438,593 to the nearest 1,000
​

6,438,593

The answer would be: 6,439,000

5 or higher gets the next number to round up meaning that because of the 5 in 593 would make the 8 in the thousands place round up to 9.

Glad I could help! (:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
