Which of the following pairs of functions are inverses of each other? O A. f(x) = 2+ and g(x) = 2 - **
O B. f(x) = 6 +8 and g(x)= 6x -8
7
O D. f(x) = 5x - 11 and g(x) -
X+11

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

pls mark as brainliest

$6.42

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
