You know that the system of equations has no solution because you get something funky when trying to solve for x like:
7 = 25
This happens because the system dont intersect.
Now there are infinite number of solutions when its the same equation (it may look different because it was multiplied by a scalar).
But in general, you will get something like
7 = 7
If you have any questions feel free to ask!

a laboratory technician needs to make a 40-liter batch of a 40% acid solution. How can the laboratory technician combine a batch
Anettt [7]
The answers comes to be for every 1 unit of pure acid (100%) add three units of 20% and you get the desired 40% 


so if you need 40 L (i don't know what container sizes there are so i can't give you an exact amount just add 1 part 100% acid and 3 parts 20% acid) <span />

General Formulas and Concepts:

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination
  • Solving systems of equations using graphing

Step-by-step explanation:

To find the solution set of a systems of equations, the point where the 2 lines intersect would show the solution for the systems.

According to the graph given, both lines intersect each other at x = -1.

Therefore, our answer is B.
