The answer is (x, y)→(x + 7, y − 7)
Answer:
There would be 15 girls and 21 boys
35 would be the answer. 45+35=80 and 45 is 10 more than 35
Assuming that this is just on a 2-D coordinate plane, we must convert the expressions on to a 3-D plane since translation cannot be done on a 2-D plane. This is done by adding a dummy coordinate that does not change. Let us use "1" for this case.
Matrix:
| 0 0 -2 |(x) = (x - 2)
<span>| 0 0 4 |(y) = (y + 4)
</span><span>| 0 0 1 |(1) = 1</span>
