Answer:
Step-by-step explanation
Substitute 2y-1 for x in the second equation:
7x + 5y = -66
7(2y-4) + 5y = -66
then solve for y:
14y - 28 + 5y = -66
19y = -38
y = -2
Substitute -2 for y in the first equation:
x = 2y - 4
x = 2(-2) - 4
x = -8
The lines intersect at (-8,-2)
Answer:
70 routes are possible
Step-by-step explanation:
Here, we want to find the number of possible routes
Since samples must be taken at four locations from a possible 8; then the number of possible routes will be 8 C 4
= 70 routes
