Answer:
Looks like the scale factor is 1/3.
Step-by-step explanation:
<em>(In this dilation, the green image is polygon ABCDE, and the red image is polygon A'B'C'D'E'. The red image is the resulting image after said dilation.)</em>
A scale factor greater than one enlarges an image, and a scale factor between zero and one shrinks an image, so that rules out options 2 (SF = -3) and 3 (SF = 3).
A negative scale factor would end up in an image opposite the center of enlargement, so that eliminates option 4 (SF = -1/3).
So that means that the scale factor is option 1 (SF = 1/3)!
Answer:
Step-by-step explanation:
Your question has typographical errors. The equation is 2a + b = 15.7, not 2e+b-15.7
2a + b = 15.7
b = 15.7 - 2a
since a > b, a = 6.3 cm
b = 15.7 - 2·6.3 = 3.1 cm
Answer:
the answer is : y=2
(btw I changed the ? into y. hope that's okay)
Answer:
7,600.
Step-by-step explanation:
The 6 is the hundreds digit - as the next digit after it is 4 we leave the 6 as it is so the answer is 7,600.
