If a number is divisible by 3 and the digits are rearranged, will the new number always be divisible by 3?

  yes

Step-by-step explanation:

The divisibility rule for 3 says the number is divisible by 3 if the sum of its digits is divisible by 3. Rearranging the order of the digits does not change their sum.

A number that is divisible by 3 will be divisible by 3 when the digits of it are arranged in any order.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
