Halla la ecuación de segundo grado de la forma \( x^{2}+\mathrm{b} x+\mathrm{c}=0 \) si \( s \) conoce la suma \( s \) el producto \( p \) de sus raices: \( \begin{array}{lll}\text { a) } s=11 \text { y } p=30 & \text { b) } s=20 \text { y } p=64 & \text { c) } s=19 \text { y } p=-120 \\ \text { d) } s=2 \text { y } p=-15 & \text { e) } s=-19 \text { y } p=60 & \text { f) } s=a \text { y } p=-2 a\end{array} \)

Solve the system if possible by using Cramer's rule. If Cramer's rule does not apply, solve the system by using another meth Write all numbers as integers or simplified fractions. \[ \begin{array}{l}7 x+7 y=-19 \\ \\ -9 x-5 y=4 \\ \text { Part: } 0 / 2 \\ \text { Part } 1 \text { of } 2 \\ \text { Evaluate the determinants } D_{1} D_{x} \text {, and } D_{y} \\ D=\square\end{array} \] \( \square \)

Find dif \( a_{1}=-17 \) and \( a_{13}=-29 \)

Question 2 of 25 After the drama club sold 100 tickets to a show, it had \( \$ 300 \) in profit. After the next show, it had sold a total of 200 tickets and had a total of \( \$ 700 \) profit. Which equation models the total profit, \( y \), based on the number of tickets sold, \( x \) ?

Use the elimination method to find all solutions of the system: \( \left\{\begin{array}{l}x^{2}-2 y=7 \\ x^{2}+5 y=14\end{array}\right. \) The two solutions of the system are: (the one with \( x<0 \) is) \( x=\square \) \( y=\square \) (the one with \( x>0 \) is) \( x=\square \) \( y=\square \)

Find the solutions. \( \left\{\begin{array}{l}x^{2}-4 y=29 \\ x^{2}+2 y=23\end{array}\right. \) > Next Question
