88° + 96° + 70° + x = 360°

254° + x = 360°

135° + 108° + x = 360°

243° + x = 360°

94° + 30° + x + 81° = 270°

205° + x = 270°

JG bisects FJH, FJG= (2x + 4)° and GJH = (3x -9)° <br> What is FJH

Kitty [74]

Hello from MrBillDoesMath!

Answer:

Discussion:

As JG bisects FJG,

FJG = GJH =>

2x + 4 = 3x-9 => subtract 2x from each side

4 = 3x -2x - 9 => simplify

4 = x - 9 => add 9 to both sides

4 + 9 = x

x = 13

Now, FJH =

FJG + GJH

(2x + 4) + (3x-9) =

5x -5 => substitute x 13

5(13) -5 =

65 - 5 =

What is the inverse of this function? (Function in photo)

valkas [14]

Given:

The function is

$f(x)=-\dfrac{1}{2}\sqrt{x+3},x\geq -3$

To find:

The inverse of the given function.

Solution:

We have,

$f(x)=-\dfrac{1}{2}\sqrt{x+3}$

Put f(x)=y.

$y=-\dfrac{1}{2}\sqrt{x+3}$

Interchange x and y.

$x=-\dfrac{1}{2}\sqrt{y+3}$

Isolate the variable y.

$-2x=\sqrt{y+3}$

$(-2x)^2=y+3$

$4x^2-3=y$

$y=4x^2-3$

Putting $y=f^{-1}(x)$ , we get

$f^{-1}(x)=4x^2-3$

For $x\geq -3$ ,

$x+3\geq 0$

$\sqrt{x+3}\geq 0$

$-\dfrac{1}{2}\sqrt{x+3}\leq 0$

$f(x)\leq 0$

It means for function $f(x)\leq 0$ and for inverse function $x\leq 0$ because the range of the function is the domain of inverse function.

Therefore, $f^{-1}(x)=4x^2-3$ for $x\leq 0$ .
