During mineral formation, the same chemical compound can be come different minerals depending on the temperature and pressure at the time of formation. A phase diagram is a graph that shows the conditions that are needed to form each mineral. The graph above is a portion of the phase diagram for aluminosilicates, with the temperature t , in degrees
Celsius $open parentheses blank to the power of ring operator straight C close parentheses$ , on the horizontal axis, and the pressure p , in gigapascals (G Pa), on the

An equation of the boundary line between the andalusite and sillimanite regions is approximated by the equation above. What is the meaning of the T-intercept of this line?

Note;
A phase diagram represents the different physical states of some substance under different conditions, such as termperature and pressure, graphically. It may seem like a complicated graph but we just needed to focus on the equation of one given line.

The budget for a school band was $straight $ 8 comma 000$ in 2010 . The budget decreased by $15 straight percent sign$ from 2010 to 2011 and then increased by $22 straight percent sign$ from 2011 to 2012 . Which of the following expressions represents the budget, in dollars, for the school band in 2012?

Note:
The concept of percentages can be a little tricky. But we just need to remember a few basic things to get going. This is the standard way of finding the value after increasing or decreasing a quantity by a certain percentage
