∆ABC and ∆PQR are similar. ∆ABC is dilated by a scale factor of 1.25 and rotated 45° counterclockwise about point B to form ∆PQR. The side lengths of ∆ABC are , 5 units; , 4.2 units; and , 4 units. Match each side of ∆PQR to its length.

Step-by-step explanation:

Given:

The scale factor =  1.25 and rotated =45°

Length of side =5 units; , 4.2 units; and , 4 units respectively.

As mention in the question the ∆ABC and ∆PQR are similar it means there sides are equal .

Therefore sides of  the ∆ PQR is  

Hence the length of the  ∆PQR is

1. minimum

2. 6400

3. eight

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
