Which of the following names a line segment in the drawing?

1 answer:

6 0

The answer is JN. A way I try to remember a line segment is that they are like two eyes with a line in the middle (sorry they make the answer 20 or more characters)

olasank [31]

Answer:

f⁻¹(x) = (x + 1) / (x - 2)
f⁻¹(1 ) = - 2

Step-by-step explanation:

Given function:

f(x) = (2x + 1) / (x - 1)

Find its inverse, substitute x with y and f(x) with x, solve for y:

x = (2y + 1) / (y - 1)
x(y - 1) = 2y + 1
xy - x = 2y + 1
xy - 2y = x + 1
y(x - 2) = x + 1
y = (x + 1) / (x - 2)

Substitute y with f⁻¹(x):

f⁻¹(x) = (x + 1) / (x - 2)

Find f⁻¹(1 ):

f⁻¹(1 ) = ( 1 + 1) / (1 - 2) = 2 / - 1 = - 2

Given rs || qp, what is the value of x?

myrzilka [38]

In the given figure,

Angle 108° + 12x = 180°

because they for pair of co- interior angles which are supplementary.

so,

$12x + 108\degree = 180\degree$

$12x = 180\degree - 108\degree$

$12x = 72\degree$

$x = \dfrac{72\degree}{12}$

$x = 6\degree$

hence , value of x = 6°
