Step-by-step explanation:
how many solutions do intersecting lines have? - 0,1 or infinitely many
how many solutions do parallel lines have? - 0 or infinitely many
if you are looking at a graph and trying to find a solution what are you looking for? - for the point(s) when the graphs intersect
Part A:
Price before tax: $49.99
Discount: 50% of $49.99 = 50% * $49.99 = 0.50 * $49.99 = $25.00
Discounted price: $49.99 - $25.00 = $24.99
Tax on discounted price: 8% of $24.99 = 8% * $24.99 = 0.08 * $24.99 = $2.00
Part B:
Total price: $24.99 + $2.00 = $26.99

Answer:

Step-by-step explanation:
Let consider that vertical axis has its positive side oriented to the north and positive side of the horizontal axis has its orientation to the east. Besides, both persons walk at constant rate. Then, displacement formulas are:
Man

Woman

The minimum distance between the man and the woman can be calculated by means of the Pythagorean Theorem:

The rate of change of such distance is:

The positions and velocities at
are:




The rate of change is:
