The system of equations shown is solved using the linear combination method
1 answer:
Answer: When a system of two linear equations gives an answer of , there are infinitely many solutions. It also means that the graph represents parallel lines, so the answer is the third choice.
Step-by-step explanation: When it comes to systems of equations in algebra, you will see three types of solutions:
1. When you get an exact value & number for x and y, the system has <u>one solution</u> and is consistent/independent.
2. When you get like in this case, the system has <u>infinitely many solutions</u> and is consistent/dependent.
3. When you get numbers that are not equal, for example, , you have <u>many solutions</u> and the system is inconsistent/independent.

The most appropriate unit to measure the mesoplankton is centimeter.
The size is 2 cm.
Step-by-step explanation:
Earlier, you found the size of a mesoplankton to be meter.
I think that meters are not the most appropriate unit to represent the size of a mesoplankton.
The most appropriate unit to measure the mesoplankton is centimeter.
Now, 1 meter is equivalent to 100 centimeters.
So, the size of the mesoplankton in centimeter units will be cm. (Answer)
