3. Calcular la inversa con el método de Gauss: \( B=\left[\begin{array}{ccc}5 & 2 & -3 \\ 0 & 8 & -1 \\ -4 & 5 & 2\end{array}\right] \)

Mathematics 1 If \( x \) varies inversel as the square root of \( y \), when \( x=27, y=9 \) 9 find the equation connecting \( x \) and \( y \) 5 find \( x \) colen \( y=10 \)

Bài 3. Viết điều kiện xác định và rút gọn các biểu thức sa s-( \( \left.x-3-\frac{x}{x-3}+\frac{9}{x}\right): \frac{2 x-2}{x} \)

19. On the set of axes below, draw the graph of the equation \( y=-\frac{3}{4} x+3 \).

Solve for x in the equation: \( \sqrt{2x - 5} + 3 = x \). Are there any extraneous solutions?

Mathematics If \( x \) taries inversely as the \( y \), when \( x=27, y=9 \) find the equation connectung \( x \)
