Answer:
D
Step-by-step explanation:
If there is a 2x2 matrix as
The determinant is given by
<em>Now, if we calculate the value of "ad - bc", we see that:</em>
We can't calculate the inverse, the inverse doesn't exist. The answer is D.
You did not attach any picture to solve this problem. We cannot calculate for the value W’X’ without the correct illustrations. However, I think I found the correct one (see attached), please attach it next time.
So the first thing we have to do is to calculate for the dilation factor. Taking point G as the reference point, we can see that the distance of point G from rectangle W’X’Y’Z’ is 1.5 while the distance from rectangle WXYZ is (1.5 + 7.5), therefore the dilation factor to use is:
dilation factor = 1.5 / (1.5 + 7.5) = 1.5 / 9 = 1/6
Since WX has an initial measure of 3 units, therefore the measure of W’X’ is:
W’X’ = 3 units * (1/6) = 0.5 units
