The line of reflection is b
You can see it much easier if take away all the clutter. Redraw the diagram and take way a d and especially c.
You should be left with only line b and the two triangles. You can see it much easier if you do that. Then just look at the parallel lines of the triangles. They are right across from each other.
Since a pentagon has 5 sides, you would divide the perimeter by the number of sides.
641.5/5 = 128.3cm
Therefore, the length of one side of the pentagon is 128.3cm.
C.) is the best answer others are less then 50%.

Hello! I would love to help!
The answer is -10,-1
Basically, you have to fill -10 in for x and -1 in for y in each equation. If the equations are true, that is the right answer!
Hope this helped! Comment if you have questions!

Answer:
graph Y
Step-by-step explanation:
The inverse function can be found by solving ...
x = f(y)
x = -3y +3
x -3 = -3y . . . . . subtract 3; next, divide by -3
y = -1/3x +1 . . . . . matches graph Y

<em>Additional comment</em>
Writing the original equation in standard form can help you see its intercepts.
3x +y = 3
3x = 3 ⇒ x = 1 . . . . x-intercept (at y=0)
y = 3 . . . . y-intercept (at x=0)
The inverse function has the x- and y-intercepts swapped, so you're looking for a line through (0, 1) and (3, 0). The lower left graph (Y) is that graph.
