A linear transformation is a function T:R^n-->R^m that satisfies the following properties
1.T(x+y)=T(x)+T(y)
2.T(ax)=aT(x)
i hoped this helped i honestly tried . let me know if im missing something
Substituting y=6x+2 into equation 3y - 18x =12 looks like:
3(6x + 2) - 18x = 12
18x + 6 - 18x = 12 distributive property left side
6 = 12 simplifying the left side
We now see a contradiction: 6 does not equal 12 What this tells us is that there is no solutions to this equation. So choice 'C' ...
c is the answer because negative numbers have to go first
63x+45x = 108x
You just multiply 3x by 21 and 15 to get 63x and 45x. You then add the like terms to get 108x.
