Point D has coordinates (4,1).What are the coordinates of Rx=2(D)

Plz which expression is equivalent to the expression below?

The vertices of a triangle are a(7.5), b(4,2), and c19. 2). what is

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
