Find m_ABD and mZCBD given m ABC = 77º. A (3x + 22) D 16 (5x - 17) B C mZ ABD |° and mZCBD

Nostrana [21]

Answer:

∠ ABD = 49°, ∠ CBD = 28°

Step-by-step explanation:

∠ ABD + ∠ CBD = ∠ ABC , substitute values

3x + 22 + 5x - 17 = 77 , that is

8x + 5 = 77 ( subtract 5 from both sides )

8x = 72 ( divide both sides by 8 )

x = 9

Thus

∠ ABD = 3x + 22 = 3(9) + 22 = 27 + 22 = 49°

∠ CBD = 5x - 17 = 5(9) - 17 = 45 - 17 = 28°

Match each function with the expression representing Its Inverse function.

USPshnik [31]

Answer:

Step-by-step explanation:

1). g(x) = -0.5x

Equation form of the given function is,

y = -0.5x

Interchange x and y,

x = -0.5y

Solve for y,

y = $-\frac{x}{0.5}$

y = -2x

Inverse function will be,

$g^{-1}x=-2x$

2). h(x) = 4x

Equation form of the function will be,

y = 4x

Interchange x and y,

x = 4y

Solve for y,

y = $\frac{x}{4}$

Inverse function will be,

$h^{-1}(x)=0.25x$

3). y = x - 4

Interchange x and y,

x = y - 4

Solve for y,

y = x + 4

Therefore, inverse of the linear equation is,

y = x + 4

4). f(x) = $\frac{x}{2}$

Equation form of the function will be,

y = $\frac{x}{2}$ = x

Interchange x and y,

x = $\frac{y}{2}$

Solve for y,

y = 2x

Therefore, inverse function will be,

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

5). k(x) = x

Equation form of the function will be,

y = x

Interchange x and y,

x = y

Solve for y,

y = x

Inverse of the function 'f' will be,

$k^{-1}(x) =x$

6). p(x) = x + 4

Equation form of the function will be,

y = x + 4

Interchange x and y,

x = y + 4

Solve for y,

y = x - 4

Inverse of the function 'p' will be,

$p^{-1}(x)=x - 4$
