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

We have to evaluate the value of the expression

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

Consider the expression,

$3+11t-9u$

= $3+(11 \times t)-(9 \times u)$

Substituting the given values, we get

= $3+(11 \times 9)-(9 \times 11)$

= $3+99-99$

= 3

So, the value of the given expression is 3.

Answer 2

Answer:

The correct answer is 3

Step-by-step 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
