Answer:
A positive times a negative will always be a negative and when u divide a positive by a negative the same rules apply so it will be a negative
The center of the dilation is the origin, and the scale factor is 2.
To find the coordinates of the points under this transformation, it is enough to multiply both coordinates of the points X, Y, and Z by 2.
Take a look at the dilation of point Z. To get to Z', both the x and y coordinate of Z must be multiplied by 2.
So, the coordinates are:
X'(8, 0); Y'(6, 4); Z'(4, -4).
Simple interest is basically the cost of borrowing money over a period of time. So if you have borrowed $110.00 at 5% for two years, you will multiply the 5% by the two years (presuming that it is 5% annual percentage rate (APR). So, You will multiply the 110 by 10% (or .1) to get $11 dollars of simple interest.
I estimated it is around or near 360
