Use the Gauss-Jordan method to solve the following system of equations. \[ \begin{array}{r}3 x-4 y+4 z=10 \\ 3 x+5 y-z=15 \\ 12 x-7 y+11 z=45\end{array} \]

3. The length of the side of a square is tripled. 3.1 Will the perimeter of the enlarged square be 3 times or 9 time of the perimeter of the original square? 3.2 Will the drea of the enlarged square be 3 times or 9 timies that area of the original square?

Given \( F \) and \( G \) are two events of an experiment with \( P(F)=0.49, P(G)=0.63 \), and \( P(F \cap G)=0.4 \), calculate the following probabilities. (a) \( P\left(F^{C}\right)= \) (b) \( P\left(G^{C}\right)= \) (c) \( P(F \cup G)= \)

Solve for \( h \) \( -3(3 h-1) \leq-7 h-5 \) \( h \geq 1 \) \( h \leq-\frac{1}{10} \) \( h \geq 4 \) \( h \leq 4 \)

The movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your The solution is \( y=3(2 y+4)=4\left(2 y-\frac{1}{2}\right) \) Th
