Business The table shows the net numbers of new stores opened by H&M from 2011 through 2015. (a) Construct a bar graph showing the annual net numbers of new stores opened by H&M from 2011 through 2015. (b) Find the n th term a n of an arithmetic sequence that approximates the data. Let n represent the year, with n = 1 corresponding to 2011. (Hint: Use the average change per year for d . ) (c) Use a graphing utility to graph the terms of the finite sequence you found in part (b). (d) Use summation notation to represent the total number of new stores opened from 2011 through 2015. Use this sum to approximate the total number of new stores opened during these years.

Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution.
Remember that:
A matrix is in row echelon form if
Any row that consists only of zeros is at the bottom of the matrix.
The first non-zero entry in each other row is 1. This entry is called aleading 1.
The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.

Please help I'm a working mom trying to help my son last minute (6th grader)! Need help with the blank ones and check the ones he got with full calculation so we can use it to study! Especially the mixed number fractions cause I'm rusty. Thanks in advance!
