In 2010 online sales were $194 billion, and in 2013 they were $248 billion. (a) Find a linear function S that models these data, where S is the sales in billions of dollars and x is the year. Write S(x) in slope-intercept form.

(b) Interpret the slope of the graph of S.

(c) Determine when online sales were $ 230 billion

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

The measure of one angle of an octagon is two times smaller that of the other seven angles. what is the measure of each angle?
