Question

solve the inequality and graph the solution.
20 + 15j ≥ -10
plot the endpoints. select an endpoint to change it from closed to open. select the middle of the segment, ray, or line to delete it.
← -5 -4 -3 -2 -1 0 1 2 3 4 5 →
submit

Explanation:

Step1: Subtract 20 from both sides

$$20 + 15j-20\geq - 10-20$$
$$15j\geq - 30$$

Step2: Divide both sides by 15

$$\frac{15j}{15}\geq\frac{-30}{15}$$
$$j\geq - 2$$

Answer:

The solution of the inequality is \(j\geq - 2\). On the number - line, we plot a closed circle at \(-2\) (because the inequality is \(\geq\)) and draw a ray to the right.
