U=F(r+B) solve for r

irina1246 [14]

<h2>The value of r = $\dfrac{U-FB}{F}$ </h2>

Step-by-step explanation:

We have,

U = F(r + B)

To find, the value of r = ?

∴ U = F(r + B)

Dividing both sides by F, we get

$\dfrac{U }{F}=\dfrac{F(r+B) }{F}$

⇒ $\dfrac{U }{F}$ = r + B

⇒ r + B = $\dfrac{U }{F}$

⇒ r = $\dfrac{U }{F}$ - B

⇒ r = $\dfrac{U-FB}{F}$

∴ The value of r = $\dfrac{U-FB}{F}$

<h3>Answer: Choice A) 1/3</h3>

================================================

Work Shown:

x = preimage length = 12

y = image length = 4

z = scale factor

z = y/x

z = 4/12

z = (1*4)/(3*4)

z = 1/3

The scale factor is 1/3.

This means the image is 1/3 of the length of the preimage.
