Answer 1

e at t=0 C = 95 11 for each hour it works = $45+ so total cost ca 45% +95 © is correct C = 454 +95 y=-²2-4 at n=10, y = 31 7x5-4 = Ž *10-4 47 © u correct Y=31 3 y=[mmte -5 pralled . lines has equal slopes slope. @ i correct 9. Gx114, y = Sat 8 both have slope y = matc R(4,-3), i.e at x= 4, y=-3 (4-41)= m(x-x.) eph of line.
