Answer:

x=4

Step-by-step explanation:

you subtract the x on both sides

6=2x-2

then you add 2 on both sides

8=2x

then divide 2 on both sides

and you get x=4

Find the inverse of f(x)=−3/2x+7/2.

Answer: $f^{-1}(x)=-\frac{2}{3}x+\frac{7}{3}$

Step-by-step explanation:

To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.

$y=-\frac{3}{2}x+\frac{7}{2}$ [replace y with x and x with y]

$x=-\frac{3}{2}y+\frac{7}{2}$ [subtract both sides by 7/2]

$x-\frac{7}{2} =-\frac{3}{2}y$ [multiply both sides by -2/3]

$-\frac{2}{3} (x-\frac{7}{2} )=y$ [distribute]

$y=-\frac{2}{3}x+\frac{7}{3}$

Now, we have our inverse function.

$f^-^1(x)=-\frac{2}{3}x+\frac{7}{3}$

Hey there! :)

Answer:

x = -7/12.

Step-by-step explanation:

Given:

$x + \frac{5}{12} = -\frac{1}{6}$

Create a common denominator for each term:

$\frac{12x}{12} + \frac{5}{12} = -\frac{2}{12}$

Disregard the denominator:

12x + 5 = -2

Subtract 5 from both sides:

12x = -7

Divide both sides by 12:

x = -7/12.
