A system of two equations can be classified as follows
Step-by-step explanation:
If the slopes are the same but the y-intercepts are different, the system has no solution. If the slopes are different, the system has one solution. If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
Answer:
No. This convenience sample is very biased and is highly unlikely to be representative of national public opinion.
Step-by-step explanation:
The sampling as per its nature should be classed as convenience sample because of its definition: this method covers part of the population with easy to reach or close to hand.

Answer: The correct option is option third .
Explanation:
The given equation are,
In the second equation the like terms are aligned, therefore, we have to aligened only first equation.
The first equation is,
Subtract 0.8 from both the sides.
Add 0.4y on both the sides.
So, after aligned the system of equation have two equations.
Both equation are show in third option, So third option is correct.
