F(x) = 2x+1/×-1 find the inverse function

denis23 [38]

To factor this, start by replacing x with y and then solve for y
$f(x) = \frac{2x+1}{x - 1}$
$x = \frac{2y+1}{y - 1}$
$(y-1)x = \frac{2y+1}{y - 1} * (y-1)$
$(y-1)x = 2y+1$
$xy -x = 2y+1$
$xy - 2y -x +x = 2y - 2y +x+1$
$xy - 2y = x+1$
Factor out y on the left side.
$\frac{xy - 2y}{y} = x+1$
$y(x - 2) = x+1$
$\frac{y(x - 2)}{(x-2)} = \frac{x+1}{x-2}$
$y = \frac{x+1}{x-2}$
$f(x)^{-1} = \frac{x+1}{x-2}$

Solve the equation ( 1 point) 3/4x=9<br><br> A) X=12<br> B) X=108<br> C) X=72<br> D) X= 4/9

Elena L [17]

Answer:

x = 12

Step-by-step explanation:

Solve for x:

(3 x)/4 = 9

Multiply both sides of (3 x)/4 = 9 by 4/3:

(4×3 x)/(3×4) = 4/3×9

4/3×3/4 = (4×3)/(3×4):

(4×3)/(3×4) x = 4/3×9

4/3×9 = (4×9)/3:

(4×3 x)/(3×4) = (4×9)/3

(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:

x = (4×9)/3

9/3 = (3×3)/3 = 3:

x = 4×3

4×3 = 12:

Answer: x = 12

PLEASE HELP WILL GIVE MANY POINTS QUICK PLEASE

Yanka [14]

Answer:

$v = 33.95m/s$

Step-by-step explanation:

Given

$h = 58.8m$ --- height

$u = 0$ --- initial velocity

$g = 9.8m/s^2$ --- acceleration

Required

The velocity when he hit the water

The velocity is then calculated using:

$v^2 = u^2 + 2gh$

This gives:

$v^2 = 0^2 + 2*9.8 * 58.8$

$v^2 = 0 + 1152.48$

$v^2 = 1152.48$

Solve for v

$v = \sqrt{1152.48$

$v = 33.95m/s$
