The Answer is C
R is (2,-1)
2*2=4
-1*2=-2
2r=(4,-2)
t=(-7,5)
-7-4=-11
5-(-2)=5+2=7
t-r=(-11,7)
Since we are multiplying r by two, we have to multiply its x and y values by two to be 2r
With t-2r, we have to subtract 2r's x value from t's x value and 2r's y value fro t's y value to get the x value -11 and the y value 7
Therefore, the x and y values for the answer is -11 and 7, and to put them in the proper form required, which is (x,y), input -11 into x's spot and 7 in y's spot, giving you and answer of (-11,7)
