Use a graphing calculator to plot the data and find the quadratic function of best fit.An engineer collects data showing the speed s of a given car model and its average miles per gallon M. Use a graphing calculator to plot the scatter diagram. What is the quadratic function of best fit? Round values to the nearest thousandth.
A. M(s) = -0.631x2 + 0.720x + 5.142
B. M(s) = -6.309x2 + 0.720x + 5.142
C. M(s) = -0.006x2 + 0.720x + 5.142
D. M(s) = 0.063x2 + 0.720x + 5.142

Solve the problem.A coffee store has available 75 pounds of A grade coffee and 120 pounds of B grade coffee. These will be blended into 1 pound packages as follow: an economy blend that contains 4 ounces of A grade coffee and 12 ounces of B grade coffee and a superior blend that contains 8 ounces of A grade coffee and 8 ounces of B grade coffee. Using x to denote the number of packages of the economy blend and y to denote the number of packages of the superior blend, write a system of linear inequalities that describes the possible number of packages of each blend. Graph the system and label the corner points.
