Celeste Tran · Answer 1

Evaluate t (1), t (2), t (3), t (4)

t (1) = 4.5 (1) - 8=4.5-8=-3.6

t (2) = 4.5 (2) - 8=9-8=1

t (3) = 4.5 (3) - 8=13.5-8=5.5

t (4) = 4.5 (4) - 8=18-8=10

the first 4 terms are

-3.6,1,5.5, 10

Karina Braun · Answer 2

Simplifying t (n) = 4.5n + - 8 Multiply t * n nt = 4.5n + - 8 Reorder the terms: nt = - 8 + 4.5n Solving nt = - 8 + 4.5n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4.5n' to each side of the equation. - 4.5n + nt = - 8 + 4.5n + - 4.5n Combine like terms: 4.5n + - 4.5n = 0.0 - 4.5n + nt = - 8 + 0.0 - 4.5n + nt = - 8 Reorder the terms: 8 + - 4.5n + nt = - 8 + 8 Combine like terms: - 8 + 8 = 0 8 + - 4.5n + nt = 0 The solution to this equation could not be determined.
