How do you solve and graph 12 ≤ t - 9 ?
How do you solve and graph ?
Answer & Explanation
First, add to each side of the inequality to solve for t while keeping the inequality balanced:
We can reverse or "flip" the entire inequality to state the solution in terms of t
To graph this we will draw a vertical line at 21 on the horizontal axis.
The line will be a solid line because the inequality operator contains an "or equal to" clause.
