Would the percentage of water in a hydrated compound determined by the experiment be too high, too low, or unchanged if during the experiment some of the compound accidentally spilled out of the crucible after the initial mass was determined? 

Solve the problem. In 2005, American spending was roughly 5.8 trillion dollars, and in 2010 American spending was roughly 6.2 trillion dollars. Let represent American spending (in trillions of dollars) and represent years since 2000. Use a linear equation model to estimate the amount of American spending in 2021. If you do not upload your work, you will receive NO credit. You must create two coordinates, find the equation between them, and plug in the appropriate value of x.

If a student recorded the temperature of boiling water to be {T1} °C and then used that same thermometer to determine the temperature of an acid solution to be {T2} °C.  What should be the corrected temperature of the acid solution?  

Provide the missing information.If a system of linear equations has infinitely many solutions, then the equations are said to be .

Solve the problem.Danielle stayed in three different cities (Washington, D.C., Atlanta, Georgia, and Dallas, Texas) for a total of 22 nights. She spent twice as many nights in Dallas as she did in Washington. The total cost for 22 nights (excluding tax) was $3,100. If we wanted to find the number of nights she spent in each city, what augmented matrix would properly represent the linear system?
