3. [-/1 Points] DETAILS MY NOTES TGEIALG6 4.1.061. Solve the system of equations by graphing. (If there is no solution, enter NO SOLUTION, If there are infinitely many solutions, enter INFINITELY MANY.) \[ \begin{array}{r}4 x-2 y=22 \\ y=2 x-11\end{array} \] \( (x, y)=(\square) \)

Solve for \( g \). \[ 10 \leq 1-g \]

11. [-/1 Points] DETAILS MY NOTES TGEIALG6 4.1.051. Solve the system of equations by graphing. (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions, enter INFINITELY MANY.) \[ \begin{array}{c}x=8 \\ 3 y=16-2 x\end{array} \] \( (x, y)=(\square \)

3. Let \( g(x)=x^{2}(x-2)^{3}(x+5) \). a) Find the multiplicity of the zero occurring at \( x=-5 \). b) Find the multiplicity of the zero occurring at \( x=0 \).

Solve for \( j \) \[ 5 \leq 6-j \]
