Which of the following pairs of functions are inverse of each other? A. f(x)=x-8/4+9 and g(x)=4(x+8)-9 B. F(x)=3(x/2)-4 and g(x)=2(x+4)/3
C. F(x)=3(2/x)-10 and g(x)=x/6+10
D. f(x)=4(x-12)+2 and g(x)=x+12/4-2
Plz help

B

Step-by-step explanation:

Y = 3x/2 - 4

replace the variables to find the inv function

x = (3y/2)-4

solve for y

×+4 = 3y/2

2(x+4) = 3y

y = 2(x+4) /3

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
