Mathematics WAEC 1999

If \(y = \sqrt{ax-b}\) express x in terms of y, a and b

  • \(x = \frac{y^2-b}{a}\)
  • \(x = \frac{y+b}{a}\)
  • \(x = \frac{y-b}{a}\)
  • \(x = \frac{y^2 + b}{a}\) checkmark

The correct answer is: D

Explanation

\(y = \sqrt{ax-b}\)

\(y^2 = ax-b\)

\(y^2 +b = ax\)

\(x = \frac{y^2 + b}{a}\)
