Combine like terms and write an equivalent expression with fewer terms. 1) `-2x 4\ - 5x`

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10

I’m really confused and need your assist me with this question i’ve never been taught
