I need help what is y2 + x + y when x=−3 and y=−4.

High schoolmathematics 5 points keith is the leading goal scorer for a team in an ice hockey league. last season, he scored 42 goals in 82 games. assuming he scores goals at a constant rate, what is the slope of the line that represents this relationship if the number of games is along the x-axis and the number of goals is along the y-axis?

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

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