Question

solve the inequality and graph the solution.

j - 20 ≥ -16

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.

Explanation:

Step1: Isolate the variable j

Add 20 to both sides of the inequality: $j - 20+20\geq - 16 + 20$.

Step2: Simplify the right - hand side

$j\geq4$.

Answer:

The solution of the inequality is $j\geq4$. On the number - line, we plot a closed circle at 4 (since the inequality is $\geq$) and draw a ray to the right of 4.
