Arental company charges a flat fee of $25 and an additional $0.40 per mile to rent a car. has to be a linear equation.

To make this a linear equation, you would do this:

It starts off already of you spent $25, even with 0 miles, so the y-intercept would be 25.

The slope would be .40x, while x = additional miles.

In the slope intercept form, it would be y = .40x + 25

The graph would be: https://puu.sh/zPyHV/880c02e660.png

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
