Answer:

x = 11, ∠ B = 71°

Step-by-step explanation:

In a parallelogram, consecutive angles are supplementary, that is

∠ A + ∠ B = 180°, thus

8x + 21 + 5x + 16 = 180

13x + 37 = 180 ( subtract 37 from both sides )

13x = 143 ( divide both sides by 13 )

x = 11

Thus

∠ B = 5x + 16 = 5(11) + 16 = 55 + 16 = 71°

Inverse for f(x)=1/2x+3

Semenov [28]

Answer: $f^{-1}(x)=2x-6$

Step-by-step explanation:

To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.

$y=\frac{1}{2}x+3$ [switch x and y]

$x=\frac{1}{2}y+3$ [subtract both sides by 3]

$x-3=\frac{1}{2} y$ [multiply both sides by 2]

$y=2x-6$

Now, we know that $f^{-1}(x)=2x-6$ .
