- 63 and b = 3 Let aj = a2 = 45 (a) Write b as a linear combination of a¡ and a2. b = a1 + a2. (b) If T:R² –→ R² is a linear combination such that T(a1) and T(a2) find T(b). тЪ) —arrow_forwardDescribe (in the form y = f(x)) the images of the lines u = 6 and v = 6 under the mapping G(u, v) = (,u? – v). (Express numbers in exact form. Use symbolic notation and fractions where needed.) image of u = 6: y = image of v = 6: y =arrow_forward25) Which notation describes the translation of the sailboat B(70, 20) to the lighthouse B'(10, 80) as a change in (x, y)? a.)
