To find the number of solutions of a system of linear equations you need to identify the slope (m) in each equation:
-If the slope is the same in both lines the system has no solution
-If the slope is different in the lines the system has one solution
-If the equation are the same (incluided the value of b) the system has infinitely many solutions
You have the next equations:
Write the equations in slope-intercept form y=mx+b (solve for y).
First equation:
Second equation:
As the equations have the same slope m = -1, the system has no solution (the line doesn't cross each other)
Answer: option C) 2,500 ml (under the assumptions shown below)
Explanation:
This is a conversion of units, but you missed the unit of the question.
What is it?
It seems it should be 2.5 liters.
So, I am going to explain you how to deal with this problem, assuming you have to find the measure equivalent to 2.5 liters.
All the choices are in mililiters (ml).
Then, you use the conversion factor 1 liter = 1000 ml
With that you do:
2.5 liter × 1000 ml / liter = 2,500 ml
And that is the choice C).
I dont know because to complicated
