Question

Need help on this algebra 2 thing. ive seen other people with the similar problem as me but not the same equations and im not sure what this is even asking me, its overdue and i have no idea how to do this
QUESTION #1
Justin sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale.
Math game: M(d)=x^2-8x-9
Reading game: R(d)=5x-39
A) solve the system algebraically. After how many days is the revenue for each game the same? Show your work and explain your answer.
B) Graph this system to show the solutions. Label each axis appropriately.

**im guessing these are like functions? i put these into desmos and got 10,11 for the points and im probably wrong but i think 10 is the days for A**

QUESTION #2
Chad drops a tennis ball from the top of a building that is 150 feet high. At the same time, his brother, Dane, launches a remote controlled plane from the base of the building upward to meet Chad.
The height of the tennis ball in feet after t seconds can be represented by the quadratic function:
b(t)=150-16t^2
the height of Dane's remote-controlled plane after t seconds can be represented by the linear function:
p(t)=25t+36
A) what are the two solutions to this system? show your work.
B) explain which solution is not reasonable in this situation.
C) after how many seconds do the tennis ball and Dane's remote-controlled plane reach the same height?

i'd love answers but would also like explanation because i have like another 3 parts to this :D
