I rounded so 9.29
good night!!
Answer:
The answer is G
Step-by-step explanation:
S=80.5km/h
D644
T8 hours
The next number should be 81*3, so 243.
1. The first equation is - 2x + 5y = 0
Second equation is
5y = 2x
- 2x + 5y = 0
Hence, the two equations are equivalent.
2.
Hence, the equations are consistent.
3.
Hence, the equations are consistent.
4. Equations can be re-arranged as:
x + y - 4 = 0 and
x + y + 6 = 0
Hence, the equations are inconsistent.
5. If we multiply the first equation by 4, we will get,
2y = -4x + 20 which is the second equation.
Hence, the equations are equivalent.
