What is the solution to the system of equations? \( y=\frac{1}{3} x-10 \) \( 2 x+y=4 \) \( (-8,6) \) \( (-6,16) \) \( (6,-8) \) \( (16,-6) \)

14. Uttrycken nedan har samma positiva värde på \( a \). Vilka tal ska stå i rutorna så att likheterna stämmer? \( a^{\frac{1}{3}}=\square \quad a^{\frac{2}{3}}=9 \)

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. \[ \begin{array}{l}7 x+7 y=-19 \\ \\ -9 x-5 y=4 \\ \text { Part: } 0 / 2 \\ \text { Part } 1 \text { of } 2 \\ \text { Evaluate the determinants } D_{1} D_{x} \text {, and } D_{y} \\ D=\square\end{array} \] \( \square \)

4. \( x^{2}-6 x+8 \leq 0 \)

5. Bestäm värdet på \( a \) så att olikheten \( 2 x-a<5 \) har lösningen \( x<7 \)

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, \( x \) ?
