Short Answer

Expert verified

The solution of the equation is $[- 40, \infty)$ and graph is shown as:-

Step by step solution

Step 1. Given Information.

The equation is $8 k \geq 5 k - 120$ .

Step 2. Solving given equation.

Solving $8 k \geq 5 k - 120$

Subtract 5k from both sides , we get:-

$\begin{array}{rcl} 8 k - 5 k & \geq & 5 k - 120 - 5 k \\ 3 k & \geq & - 120 \\ \frac{3 k}{3} & \geq & \frac{- 120}{3} \\ k & \geq & - 40 \end{array}$

Therefore, The solution in interval notation is $[- 40, \infty)$ and graph is shown as :-
