The bar graph shows that in 2000 and 2001 , the U.S. government collected more in taxes than it spent, so there was a budget surplus for each of these years. By contrast, in 2002 through \(2009,\) the government spent more than it collected, resulting in budget deficits. Exercises \(79-80\) involve these deficits. (GRAPH CANT COPY) a. In \(2006,\) the government collected \(\$ 2407\) billion and spent \(\$ 2655\) billion. Find \(2407+(-2655)\) and determine the deficit, in billions of dollars, for 2006 b. In \(2007,\) the government collected \(\$ 2568\) billion and spent \(\$ 2730\) billion. Find the deficit, in billions of dollars, for 2007 . c. Use your answers from part (a) and (b) to determine the combined deficit, in billions of dollars, for 2006 and 2007
Why is it that 0 has no multiplicative inverse?
Describe what it means to raise a number to a power. In your description, include a discussion of the difference between \(-5^{2}\) and \((-5)^{2}\)
Write each phrase as an algebraic expression. a loss of half of an investment of \(d\) dollars
In each exercise, determine whether the given number is a solution of the equation. $$-\frac{1}{2}=x-\frac{2}{3} ; \frac{1}{6}$$
