Perpendiculare means the slopes multiply to -1
y=3/5x+10
slope is 3/5
3/5 times what is -1
-5/3 is answer
slope of perpenduclar is-5/3 find y int
y=-5/3+b
point given is (15,-5)
x=15
y=-5
-5=-5/3(15)+b
-5=-25+b
add 25 to both sides
20=b
the yintercept is y=20 or the oint (0,20)
Answer:
I believe the answer is d
The answer depends on what type of division it is. Synthetic?
The exterior angles of a polygon all add to 360, if you need to find an exterior angle when given the number of sides and that all angles are equal you simply do: 360/ number of sides.
When you need to find the exterior angle when given an interior angle, you do: 180- interior angle.
Hope this helps :)
