Answer:

  y was not substituted for every x

Step-by-step explanation:

To find the inverse of ...

  y = f(x)

you need to solve ...

  x = f(y)

Here, f(x) = x^2 +12x, so f(y) = y^2 +12y

This is not the expression we see on the right of ...

  x = y^2 +12x

Apparently y was not properly substituted into f(x).

Find the missing value.<br> (√24-√k)(√24+√k)=5
Anna [14]

Answer:

  • <u>k = 19</u>

Step-by-step explanation:

<u>Identity</u>

  • (a + b)(a - b) = a² - b²

<u>Simplifying the LHS (Left Hand Side)</u>

  • (√24-√k)(√24+√k)
  • (√24)² - (√k)²
  • 24 - k

<u>Equating to the RHS</u>

  • 24 - k = 5
  • k = 24 - 5
  • <u>k = 19</u>
