45% * x=72

45/100 *x=72

45x/100=72

45x=7200 /:45

x=160

⇒72 is 45% of 160.

$\frac{72}{x} = \frac{45}{100}$
^^^^^percent proportion^^^^^^^
multiply 72 x 100 = 7200
divide 7200 ÷ 45 = 160
72 is 45% of 160.

Plot the image of D under a dilation about the origin (0,0) with a scale factor of 2

ElenaW [278]

(-6,-4)

If you dilate a point, (c,d) about (a,b) by a scale factor by k. You'll going to subtract each coordinates where the point will be dilated about (a,b) from the point (c,d) and then multiply them by k. This would be the formula if you want: (k(c -a), k(b -d))

Let's say F is the dilation of D about the origin or (0,0) then the x coordinate of F would be

$x = 2( - 3 - 0) \\ x = 2( - 3) \\ x = - 6$
