Question
Solve each inequality and graph the solution :
Hint:
Linear inequalities are expressions where any two values are compared by the inequality symbols<,>,≤&≥ .
We are asked to solve the inequality and graph it.
The correct answer is: 9>x
Step 1 of 2:
Find the LCM of the inequality;
Take out the three from the inequality;
2x+42-9x>-21
Now, rearrange and solve the inequality;
Step 2 of 2:
Graph the solution of the inequality;
When we have an inequality with the symbols , we use dotted lines to graph them. This is because we do not include the end point of the inequality.

Which of the following expresses the riser height in terms of the tread depth?
When designing a stairway, an architect can use the riser-tread formula 
, where h is the riser height, in inches, and d is the tread depth, in inches. For any given stairway, the riser heights are the same and the tread depths are the same for all steps in that stairway.
The number of steps in a stairway is the number of its risers. For example, there are 5 steps in the stairway in the figure above. The total rise of a stairway is the sum of the riser heights as shown in the figure.
