How do you solve and graph 12 t - 9 ?

Answer & Explanation




2022-07-04Added 11 answers

Step 1
First, add 9 to each side of the inequality to solve for t while keeping the inequality balanced:
12 + 9 t - 9 + 9
21 t - 0
21 t
We can reverse or "flip" the entire inequality to state the solution in terms of t
t 21
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.
