Triangle XYZ with vertices X(3,-1) Y(7,-3)Z(3,-5) undergoes an enlargement represented by the mapping:

(x)--(-0.5 0)(x) +(-3)

(y)--( 0 -0.5)(y) +(4)

Evaluate:

1. The vertices of the image of triangle XYZ.

2. The centre of enlargement

PS. The small brackets should be one big bracket for matrices but I don't have it on the computer.
