Y = -1/2x - 1
Tell me if you need explanation
Answer:
Rate is 9 kilometers (km)/week.
Step-by-step explanation:
9000 meters is 9 km (divide m by 1000 to get km)
Step-by-step explanation:
2x = y-10
Rewrite as: 2x + 10 = y
Therefore:
2x+10 = y
2x +7 = 2y
Subtract the equations:
2x + 10 = y
- 2x + 7 = 2y
______________
3 = -y
Therefore y = -3
Substiture y = -3 into the second equation:
2x + 7 = 2(-3)
2x + 7 = -6
2x = -13
x= -6.5
Answer : (-6.5, -3)
