In which variable is (3t-8) a linear polynomial?
Answer and explanation
Correct answer: t
In \(3t-8\), the only variable present is \(t\). Its highest power is 1, so it is a linear polynomial in \(t\). The variables \(x\), \(y\), and \(z\) do not occur in the expression, so the polynomial is not described as linear in them. Exam tip: a linear polynomial has highest degree 1 in its variable.
