The linear function E(t) that fits data is? (Round to the nearest tenth)Use the function to predict the life expectancy of males in 2004? (Round to the nearest tenth)5x + 2y = 9 and 5x + 2y = 1The total cost for 3 months of service is?If a customer has only $90 available how many months of service can she receive?Graph for the equation c = 30t + 206x 7y = 21 7y 6x = -21What is the solution of the system of equations? Is it no solution? Is it a point? Or is it infinitely many solutions?Is the system consistent or inconsistent?Are the equations dependent or independent?5x + 6y = 410x + 12y = 83r 5s = -125r + 3s = 14
