Okay. So in order to solve this problem, we really have to try out each answer and divide it by 9. A is not correct, because it does not divide evenly. B works, but let's check the others. C and D do not work, but E also works as well. If you can have two answers, 504 and 882 are both exactly divisible by 9. The answers are B: 504 and E: 882.
What do you need help with?
9n - 2 - 6n - 3
(9n + -6n) + (-2+-3)
=3n -5
well the name of the phase for that is called freezing. I think that's we have to look for, maybe not, but I hope I helped
By changing the sign of x coordinates the point would be reflected along "y" axis.
Step-by-step explanation:
Let us plot a hypothetical point (x, y) where both x and y are positive integer. Since both the number sets are positive integer, hence the points lie in 1st quadrant.
Now we change the sign of the x coordinates i.e. x=-x
The new coordinates are (-x, y)
since x is negative and y is positive hence this set would lie in 2nd quadrant.
Comparing the above two pointset (x, y) and (-x, y)
We find that 2nd set is the reflection of the 1st set along y axis (“y” remains constant and sign of “x” coordinates change)
Hence if the original point is in 1st quadrant then the after changing the sign points would lie in 2nd quadrant and vice-versa.
Similarly, if both the values of “x” and “y” are negative i.e. points lie in 3rd quadrant, then the points would lie in 4th quadrant after changing and vice-versa
