In the diagram shown, ∆CDE was mapped to ∆C, D, E using a sequence of two ridged motion transformations. The first was a translation of ∆CDE six units right and eight units up. The second was a reflection across a line. Determine the equation of the line of reflection. Show how you arrived at your answer.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

a: inscribed angles

i reviewed this question with a peer and teacher, seems to be correct, me later

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
