Jolene invests her savings in two bank accounts, one paying 3 percent and the other paying 10 percent simple interest per year. She puts twice as much in the lower-yielding account because it is less risky. Her annual interest is 7456 dollars. How much did she invest at each rate? Amount invested at 3 percent interest is \( \$ \) Amount invested at 10 percent interest is \( \$ \)

Ejercicio z: Dilatación de un cuadrado con facior Problema: Diata el cuadrado con vérices \( A(2,2) \), \( B(4,2), C(4,4) \), y \( D(2,4) \) usando un factor de escala k=3 respecto al origen.

Find the value of \( k \) that makes \( f(x) \) continuous at \( x=-1 \) \[ f(x)=\left\{\begin{array}{ll}\frac{x+1}{x^{2}+3 x+2} & \text { if } x \neq- \\ k & \text { if } x=-\end{array}\right. \] \( k=\square \)
