\( h(x)-5^{x-4}+2 \)

1. Sea la matriz \( A=\left(\begin{array}{ccc}-1 & 2 & \mathrm{k} \\ 2 & -3 & -3 \\ 3 & -5 & 0\end{array}\right) \) Hallar los valores de k para los cuales la matriz A es inversible.

John is 70 years younger than Sharon. Sharon is 4 times as old as John. If you let \( s= \) Sharon's age and \( j= \) John's age, then the problem can be represented by a system of equations. Which of the following show graph of this system and the solution to this problem?

\( \left. \begin{array} { l } { \{ ( - 4 , - 2 ) , ( - 1 , - 1 ) , ( - 1,1 ) , ( 3,5 ) , ( 7,10 ) \} } \\ { \{ ( - 6,4 ) , ( - 3 , - 2 ) , ( 0,5 ) , ( 1 , - 2 ) , ( 2,3 ) \} } \\ { \{ ( - 8,3 ) , ( - 6,5 ) , ( - 4,2 ) , ( - 2,7 ) , ( - 1,4 ) \} } \\ { \{ ( 5,0 ) , ( 4,0 ) , ( 3,0 ) , ( 2,0 ) , ( 1,0 ) \} } \end{array} \right. \)

Solve the equation and each inequality. Use interval notation to write solution sets to the inequalities \( \begin{array}{lll}\text { (a) } k^{2}-11=0 & \text { (b) } k^{2}-11 \leq 0 & \text { (c) } k^{2}-11 \geq 0\end{array} \)
