Answer: For lines to be parallel, the slope has to be the same.

For lines to be perpendicular, the slope has to be the negative reciprocal.  4 x + 2 y = 7

2 y = − 4 x + 7

y = − 2 x + 7 /2

Compared to : y = 2 x − 3

Step-by-step explanation: Just a good guess.

For the standard normal curve, find the z-score that corresponds to the 30th percentile. -0.47 -0.98 -0.53 -0.12
Nata [24]
We are looking for the Zo score that corresponds to the 30th percentile.
 We use the table for the standard normal distribution.
 From P (Z <Zo) = 0.3 we search for Zo.
 Then we look in the table for the value of Zo that corresponds to 0.3.
 Hence, the approximate value is -0.53.
 The option is the third

F(x)=2x+1/x-1 then f^-1(1)​
olasank [31]

Answer:

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

Step-by-step explanation:

<u>Given function:</u>

  • f(x) = (2x + 1) / (x - 1)

<u>Find its inverse, substitute x with y and f(x) with x, solve for y:</u>

  • 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)

<u>Substitute y with f⁻¹(x):</u>

  • f⁻¹(x) = (x + 1) / (x - 2)

<u>Find  f⁻¹(1 ):</u>

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