What property is 4x + 40 - 40 = 16 - 40

The photo show how to solve the equation. Also you can use calculator to solve the problem. The easiest way of doing this is using a scientific calculator then use shift solve method for the ans

Well.. if we assume the maximum distance the plane is capable of traveling is our flight from ca to au then the speed of the plane is: 14,430/16 = 901.875 km/hr g(t) = 422,000 - 901.875t where t is time (x-axis, hr)g(t) is the gas left in the plane (gal)make sure to label your axis. - plot intercepts (0, 422,000) and (16, 0) then draw a line connecting them. linear model is a line graph
