4x−5=7+4y

subtract 7 from both side

4x - 5 -7 = 4y

4x -12 = 4y

divide by 4

4x/4 -12/4 = 4y/4

x-3=y

Answer:

y = x - 3

Step-by-step explanation:

Given equation,

4x - 5 = 7 + 4y

For finding the equation for y,

We need to isolate y in the left side of the equation,

Now,

Add 5 on the both sides of the above equation,

4x = 7 + 4y + 5

Subtract 4y on the both sides,

4x - 4y = 12

Subtract 4x on both sides,

-4y = 12 - 4x

Divide both sides by -4,

$y=x-3$

What is the inverse of f(x)=(x+6)2 for x≥–6 where function g is the inverse of function f? g(x)=x√−6, x≥0 g(x)=x−6−−−−√, x≥6 g(x

avanturin [10]

Answer:

$g(x)=\sqrt{x}-6$ , x>=0

Step-by-step explanation:

$f(x)=(x+6)^2$

To find the inverse function , replace f(x) by y

$y=(x+6)^2$

Replace x with y and y with x

$x=(y+6)^2$

Solve the equation for y

take square root on both sides

$+\sqrt{x} =y+6$

Now subtract 6 from both sides

$+\sqrt{x}-6=y$

replace y with g(x)

$g(x)=\sqrt{x}-6$
