In the figure above, RT = TU. What is the value of x?

For the graph below , write an inequality and explain the reasoning :

Note:
We do not use < or > for infinity in inequalities, since the variable extends to infinite and has no real fixed value.

The formula below is often used by project managers to compute E, the estimated time to complete a job, where O is the shortest completion time, P is the longest completion time, and M is the most likely completion time.

Which of the following correctly gives P in terms of E, O, and M?

A square has vertices (0, 0), (3, 0), and (0, 3). Find the fourth
Vertex.

Let a, b and c be real numbers, c≠0, Show that each of the following statements is true :
1. If a>b and c<0 , then ca< cb
2. If a>b and c<0 , then .

Note:
Whenever we multiply or divide an inequality by a negative number, the direction of the inequality symbol changes.
