Answer:
The lines are reflections of each other.
Step-by-step explanation:
The slope of the first line is 2/5.
The slope of the second one is -2/5.
The lines are reflections of each other.
The slope/intercept form of the equation of a straight line is
Y = (slope) X + (y-intercept) .
You know the slope and the y-intercept.
All you have to do is take that equation and fillum in.
Answer:
He would gain by choosing air travel if, and only if, he values his time at more than $5 per hour.
Step-by-step explanation:
The problem states that:
A bus ticket from Washington to St. Louis costs $100, while it takes 32 hours to arrive.
A plane ticket from Washington to St. Louis costs $250, while it takes 2 hours to arrive.
Other things constant, Andrew would gain by choosing air travel if, and only if, he values his time at more than
If Andrew choses to go by plane, he saves 32-2 = 30 hours at the expense of $250-$100 = $150.
So, dividing the extra cost by the number of hours saved:

He would gain by choosing air travel if, and only if, he values his time at more than $5 per hour.
Answer:
23.274
Step-by-step explanation:
Here, rounding to the nearest thousandth means rounding to the nearest 0.001.
Hence, due to the digit being rounded having a number larger than 5 after it (0.2736), it is rounded up.
Hope this helped!
