Solve x2 + 13x + 22 = 0 using the quadratic formula.

Without graphing the linear functions, find the coordinates of the point of intersection of their graphs: y=3x−11 and y=4

Two lines that do not intersect are skew. always sometimes or never

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities
