Question

Evaluate 3 + 1 1 t − 9 u 3+11t−9u3, plus, 11, t, minus, 9, u when t = 9 t=9t, equals, 9 and u = 1 1 u=11u, equals, 11.

Answer 1

The correct answer is 3

Explanation:

Given the function

f(t, u) = 3 + 11t - 9u

To get the value of the function when t = 9 and u = 11, we will substitute the given variables into the given function to have;

f(9, 11) = 3 + 11(9) - 9(11)

f(9, 11) = 3 + 99 - 99

f(9, 11) = 3

Answer 2

We have to evaluate the value of the expression

`3+11t-9u` at t=9 and u=11

Consider the expression,

`3+11t-9u`

=
`3+(11 * t)-(9 * u)`

Substituting the given values, we get

=
`3+(11 * 9)-(9 * 11)`

=
`3+99-99`

= 3

So, the value of the given expression is 3.
