An octagon has a perimeter of 28 units. What is the perimeter of the image of the octagon after the translation
(x, y) —> (x-7,y+6), a rotation 90° clockwise, and a reflection across the y-axis?

answer:   c ?

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is
