Answer:
1 is 5 degrees
2 is 600
3 is 90
Step-by-step explanation:
i used a calculator idk
F(x) = 15x + 50/x + 5
y = 15x + 50/x + 5
x = 15y + 50/y + 5
x(y + 5) = 15y + 50
xy + 5x = 15y + 50
5x - 50 = 15y - xy
5x - 50 = y(15 - x)
y = 5x - 50/15 - x
SO
The inverse of f(x) = 5x - 50 over 15 - x

First we will obtain the original coordinates
A = (-3, 4)
B = (-1, 4)
C = (1, 1)
D = (-5,1)
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).
The reflection of the point (x,y) across
the line y = -x is the point (-y, -x).
A' = (-4, 3)
B' = (-4, 1)
C' = (-1, -1)
D' = (-1, 5)
