Answer:
let ABC be a right-angled triangle, where A is the right angle (left to right)
the original coordinates:
A (-8, 8)
B (-1, 8)
C (-8, 5)
by changing the coordinates from (x, y) to (-y, x)
A (-8, -8)
B (-8, -1)
C (-5, -8)

Answer:
Step-by-step explanation:
Solve we have the inequality:
Let's solve it like a normal equation first. So, pretend the inequality is an equal sign:
Solve for x. Zero Product Property:
Add 4 to both sides for both equations:
So, our roots are at x=4 and x=4.
Since our original inequality is <em>greater than</em>, this means that our solution will be all values to the <em>left</em> of our first zero and all values to the <em>right</em> of our second zero.
Therefore, our solution is:
Simply put, our x can be anything except for 4 itself.
And we're done!
