Issouf claims that the scale factor is 1/2. which statement about his claim is correct?

A- He is correct because CB is 4 and C' B' is 2. The scale factor is C'B'/CB = 2/4 = 1/2

B- He is correct because he needs to subtract 2 from each side. A reduction has a scale factor that is a fraction, so it must be 1/2

C- He is Incorrect because it is 3. CB is actually 2+4 or 6. So one needs to multiply the pre-image length by 3 to get the image; 3 is the scale factor.

D- He is Incorrect because the scale factor is 1/3. CB is actually 2 + 4 = 6. CB is the pre-image, so the scale factor is C'B'/CB = 2/6 = 1/3.​

Answer :

Answer:

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

[tex]CB'=C'B'=2[/tex]

[tex]B'B=6[/tex]

[tex]CB=CB'+B'B=2+4=6[/tex]

The scale factor of a figure is

[tex]k=\frac{\text{Length of any side of image}}{\text{Length of corresponding side of preimage}}[/tex]

[tex]k=\frac{C'B'}{CB}[/tex]

[tex]k=\frac{2}{6}[/tex]

[tex]k=\frac{1}{3}[/tex]

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

Therefore the correct option is D.
