Solve the equation for x by graphing. -4x-1=5^x+4

x=-1.282

Step-by-step explanation:

To solve the equation by graphing, you have to plot graphs of two functions:

The x-coordinate of the point of intersection is the solution of the equation.

The graph of the function is shown in attached diagram with red line and the graph of the function is shown with blue curve.

The point of intersection has approximate coordinates (-1.282, 4.127), so the solution (correct to three decimal places) of the equation is x=-1.282

The correct answer here is that there were originally 60 miles on car B. We can work this out with the following equation -

A = B - 50B = C + 30A + 50 = BB+ 50 = C + 802A = 3C - 70

Solution: A = 110, B = 60, C = 30
