Find the value of k so that the point (k,5) lies on the line represented by 2x -y = 10

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1

Polynomials plz quick 1: subtract and simplify (–y^2 – 4y – 8) – (–4y^2 – 6y + 3)

The equation ip| = 2 represents the total number of points that can be earned or lost during one turn of a game. which best describes how many points can be earned or lost during one turn?
