C I am soooo sorry if I’m wrong
The inverse function
is such that

If
, then we have

Solve for the inverse :

Pi x D = circumference
Radius x 2 = diameter
8 x 2 = 16
16 x pi = 50.26548246
we are given
we know that
sum of all angles in any quadrilateral is 360
so, we can write it as

now, we can combine it

now, we can subtract both sides 258


so, this is FALSE..........Answer
Answer:
x = -2, y =-2
Step-by-step explanation:
5x - 6y = 2
-5x - 5y = 20
Add the two equations together to eliminate x
5x - 6y = 2
-5x - 5y = 20
------------------------
-11y = 22
Divide by -11
-11y/-11 = 22/-11
y = -2
Now we can find x
5x -6(-2) =2
5x +12 = 2
Subtract 12 from each side
5x +12-12 =2-12
5x = -10
Divide by 5
5x/5 = -10/5
x = -2
