Help me pls. Only answer if your sure you know what you're doing.

1. Mrs.Galicia bakes and then sells cookies and brownies from her bakery. Her revenue for each baked good (in dollars) is modeled by the equations, where x is the number of days since the baked goods started to sell.
Brownies: () = 2ଶ + 8 − 4
Cookies: () = 2 + 4

Solve the system algebraically. After how many days is the revenue for each item the same? Show your work and explain your answer.

2. Mrs.Galicia dropped a ball from the top of a tower. At the same time, her son, Antonio, launches a rocket from a different level of the tower. The height of the tennis ball in feet after t seconds can be represented by the quadratic function: () = −^2 −4 + 22.

The height of Antonio's rocket after t seconds can be represented by the linear function: () = −2 + 12.

(a) What are the two solutions to this system? Show your work algebraically.
(b) Explain which solution is not reasonable in this situation.
(c) After how many seconds do the rocket and the ball reach the same height.
