Answer 2

To evaluate the expression T(t+7)-(8+1) when t = 8/9, you can substitute the value of t into the expression and perform the calculations as follows:

T(t+7) - (8+1) when t = 8/9

First, calculate T(t+7) with t = 8/9: T(8/9 + 7) = T(8/9 + 63/9) = T(71/9)

Now, substitute this value back into the expression:

T(71/9) - (8 + 1)

You can leave the first term as it is because it's already in simplified form:

T(71/9) - 9

So, the simplified expression when t = 8/9 is T(71/9) - 9.
