Given:
The point is B(2,5) and its image is B'(1,2.5).
To find:
The scale factor.
Solution:
If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as

x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is

Therefore, the scale factor is
and the correct option is D.
Hey there!
Make the 2% to a decimal which is .02 and multiply it by 57 to find the sales tax
.02*57= 11.4
So 11.4 is the sales tax
So add 11.4 to 57 and you get
$68.40 is the total cost
Hope this helps!
Hello, there!
He could use answer D. 8 feet by 3 feet.
The formula for area of a rectangle is L * W = A
The length is 8 and and the width is height
8 * 3 = A
8 * 3 = 24
Therefore, the answer is D.
I hope helped!
