Answer:
number of hours = 3 hours
Step-by-step explanation:
Let
x = number of hours
Casa Lucia = 200 + 500x
Silver Fox = 1,100 + 200x
To solve the equation, equate both cost of rent
Casa Lucia = Silver Fox
200 + 500x = 1,100 + 200x
200 - 1,100 = 200x - 500x
-900 = - 300x
x = -900 / -300
x = 3 hours
number of hours = 3 hours
The solution to the system of equations in this real-world context represents the number of hours both locations can be rented with the same cost.
It means both locations cost the same if rented for 3 hours each
The normal vectors to the two planes are (3, 3, 2) and (2, -3, 2). The cross product of these will be the direction vector of the line of intersection, (12, -2, -15).
Using x=0, we can find a point on this line by solving the simultaneous equations that remain:
... 3y +2z = -2
... -3y +2z = 2
Adding these, we get
... 4z = 0
... z = 0
so the point we're looking for is (x, y, z) = (0, -2/3, 0). This gives rise to the parametric equations ...
- x = 12t
- y = -2/3 -2t
- z = -15t
By letting t=2/3, we can find a point on the line that has integer coefficients. That will be (x, y, z) = (8, -2, -10).
Then our parametric equations can be written as
- x = 8 +12t
- y = -2 -2t
- z = -10 -15t
