t + 12 ≤ 20. Solve and graph the solution.

Question

If possible please describe if the circle is open or closed, what number does the circle go on and does the arrow point to the left or right.

Thank you.

Answer 1

First step is to solve the inequality for t.

t+12≤20

t ≤ 8

Now we can look at graphing it.

Since it is ≤ and not < we know that the circle is closed.

If we read the inequality it says "t is less than or equal to 8."

This means t is less than 8 so the arrow points to the left.

Hope this helps!
