Answer:
b. The supplements of congruent angles are congruent
Explanation:
Note that

is a supplement of

and

is a supplement of

.
Since

,

because
the supplement of the congruent angles are congruent.
f(x) = -5x - 15
Let y = f(x)
y = -5x - 15
Switch the x and y places, and solve for y:
x = -5y - 15
-5y = x + 15
y = (x + 15)/-5
y = -(x/5) - 3
So the inverse of : f(x) = -5x - 15 is
-x/5 - 3
Phone card = $20
You need to minus 17.92 from 20 = $2.08
$2.08 / 0.13 = how many minutes
