Answer:
(x,y) maps to (-y,x).
Step-by-step explanation:
Use vertex I as an example.
Pre-image I is graphed at point (-3,2), while image I' is graphed at point (-2,-3) .
In order to change between these points, the x and y coordinates must be swapped, as well as multiplying the y coordinate by -1.
There are many solutions. infinite solutions at that. when you solve it it equals itself 2.5w+21= 2.5w+21 so that means all numbers would work as a solution.
Answer:r
=8 in
Step-by-step explanation:
A=π⋅r2 64π=π⋅r2
Divide by pi on both sides
64=r2
r=8 and−8 but since distance can't be negative, the answer is just 8
