Answer:
The coordinates of EF are E(5,-4) and F(1,-4).
The line segment EF is in QIV
Step-by-step explanation:
The line segment AB has vertices at: A(-4,5) and B(-4,1).
We apply the rule
to reflect AB in the y-axis to obtain CD.


We apply the rule
to rotate CD 90 degrees clockwise about the origin to obtain EF.


The coordinates of EF are E(5,-4) and F(1,-4).

Determine the average rate of change
Average rate is calculated as thus;

<em>In this case; b = 12 and a = 6</em>
Calculating f(12)



Calculating f(6)



Substitute 12 for b and 6 for a in 

Substitute values for f(6) and f(12)



Answer:
x = 8
Step-by-step explanation:
you have similar triangles here
so 2 is to 4 as 4 is to x
2/4 = 4/x
x = 8
