Question

line segment qr is dilated to create line segment qr using the dilation rule ( d_{t,1.5} ). what is y, the distance between points r and ( r )? 3 units 4 units 6 units 9 units

Explanation:

Step1: Use dilation formula

Dilation formula \(TR'=TR\times scale\ factor\). Given \(TR = 6\) and scale factor \(1.5\).

$$TR'=6\times1.5 = 9$$

Step2: Calculate \(y\)

\(y=TR'-TR\)

$$y = 9 - 6=3$$

Answer:

3 units
