Answer: (-4,-1), (-2,-1), (-5,-4), and (-1,-4)
Step-by-step explanation: The formula for finding the rotation of points on a graph depends on how far you want to rotate the point; r90°(x,y) = (-y,x), r180°(x,y) = (-x,-y), and a r270°(x,y) = (y,-x).
r180°(1,4) = (-1,-4) r180°(5,4) = (-5,-4) r180°(2,1) = (-2,-1) r180°(4,1) = (-4,-1)
I hope this helps, have a nice day.
Answer:
A! The polygon was dilated, then reflection vertically!
Here’s how you can set up the problem:
10 + 25d = 40 + 10d
(d means pages per days)
15d = 30
D = 2
So, the answer would be two days. You can check this by plugging it into the problem:
10 + 25(2) = 40 + 10(2)
10 + 50 = 40 + 20
60 = 60; correct!
Hope this helped! :)
4/12 = 3/9
12/20 = 3/5
6,5/5 = 13/10
5/10 = 8/16
The incenter of a triangle is equidistant from all sides of the triangle
The incenter is the center of the biggest circle that can be drawn in the triangle, and is called incircle
The incircle will be tangent to all sides of the triangle.
Observation:
In an equilateral triangle the incenter, circumcenter, and centroid are all the same
