Answer:
Company A: 
Company B: 
Step-by-step explanation:
The initial fee is the y-intercept, as that is the cost at x = 0, or the cost before any time has passed. Afterwards, the rate the cost increases is the slope.
Linear equation in slope-intercept form:

where m is the slope and b is the y-intercept.
Company A charges $50 up front and $40 per hour afterwards, so the equation would be:

Company B charges $25 up front and $50 per hour, so:

(11x408) / 16 = 280.5 miles on 11 gal of gas
Any integer number multiplied by 2 is even. So if you add 1 to an even number it becomes odd
Answer:
I can relate to "dude lengths"
Step-by-step explanation: Add all the side lengths to total the perimeter:
P= 2x+4x-2+3x-1
Simplify by combining like terms:
P= 9x -3
If you were given a value for P or x you could solve the equation
