Question

Alguém pode me ajudar com essa questão??

Sendo f(x) = x + 7 e g(x) = 3x - 1, determine os valores reais de x para que se tenha
f(x) ≥ g(x)

Answer 1

$\left\begin{array}{ccc}f(x)&\ge&g(x)\\\\\\x+7&\ge&3x-1\\\\\\x-3x&\ge&-1-7\\\\\\-2x&\ge&-8\\\\\\2x&\le&8\\\\\\x&\le&\frac{8}{2}\\\end{array}\right\\\\\\\\\boxed{x~\le~4~~~~ou~~~~x\in~]-\infty~,~4]}$
