Answer:

w = -4

Step-by-step explanation:

-11w + 7 + 10w = 19 + 2w

-1w + 7 = 19 + 2w

-1w + 1w + 7 = 19 + 2w + 1w

7 = 19 + 3w

7 - 19 = 19 - 19 + 3w

-12 = 3w

$\frac{-12}{3} = \frac{3w}{3}$

-4 = w

1. Gather like terms
-w + 7 = 19 + 2
2. Move terms
-w -2w = 19 - 7
3. Subtract
-3w = 12
4. Divide both sides by -3
w = -4

What’s the inverse of f(x) = -2 + 2/3x

saveliy_v [14]

So the steps to find the inverse are:

Change f(x) to y
Switch the positions of x and y
Solve for y
Change y to f^-1(x)

$f(x)=-2+ \frac{2}{3}x\\\\y=-2+ \frac{2}{3}x\\\\x=-2+ \frac{2}{3}y$

Now let's solve for y as such:

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

Your inverse is f^-1(x) = 3/2x + 3
