If a point is located above the xy-plane, then which coordinate(s) must be positive?

Aline parallel to a triangle's side splits ab into lengths of x - 5 and x + 2. the other side, ac, is split into lengths of x and x + 12. what is the length of ac? a) 12 b) 24 c) 36 d)

What is the distance between the points (2 -3) and (-6 4) on the coordinate plane

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
