Respuesta :
10r + s -t = ⟨73, 15⟩
What are coordinates?
Coordinates are two numbers (Cartesian coordinates), or sometimes a letter and a number, that locate a specific point on a grid, known as a coordinate plane.
Given:
r = ⟨7, 1⟩, s = ⟨–6, 2⟩, and t = ⟨–9, –3⟩.
10r + s -t
=10(7,1 ) + (-6, 2) - (-9, -3)
=(70 - 6 + 9 , 10 + 2 + 3)
= (73, 15)
