Which classification describes the system of linear equations?
1 answer:
Answer:
Inconsistent
Step-by-step explanation:
Consistent independent means that there is only one solution; ie one place where the 2 lines intersect.
Inconsistent means that the lines will NEVER cross because they are parallel
Consistent dependent means that the 2 lines, when solved for y, are the exact same line (same slope, same y-intercept)
In our system, one of the equations is already solved for y, so let's solve the other one for y:
so
and
The slopes of the 2 lines are the same; therefore, they are parallel and will never intersect. Inconsistent system.

Answer:
of oil.
Step-by-step explanation:
Firstly, you need to find the LCD (lowest common denominator), this can be done by factoring the denominators and knowing the multiples.
In this case, you can see that 2 is a factor of 8 so we can simply multiply so that the denominator is 8:
8 ÷ 2 = 4
Now the fractions can be added easily:
= of oil.
Hope this helps!
