Which of the following pairs of functions are inverses of each other? A. f(x)= =+8 and g(x) = 2x - 8
18
O B. f(x) =
18
9 and g(x) =
X +9
=
X
O C. f(x) = 3x2 +16 and
g(x) =
- 16
x + 10
D. f(x)= 8x8 – 10 and g(x) = :

5 3200sq,ft

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
