A train travels at (3x + 5) miles per hour for 4 hours. Write an expression showing this.

If x = 4, how far did the train travel in four hours?

Graph the equationy= x+3[tex]y = x + 3[/tex]

Dean and karlene get paid to write songs. dean is paid a one-time fee of $20 plus $80 per day. karlene is paid a one-time fee of $25 plus $100 per day. write an expression to represent how much a producer will pay to hire both to work the same number of days on a song.

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
