URGENT!!! PLEASE HELP

Mathematics
1 answer:
Molodets [167]3 years ago

Answer: System 1 has an infinite number of solutions and System II has no solutions.

Step-by-step explanation:

If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.

If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

10 days is twice the half-life. After 5 days, can expect \dfrac{25}2 grams to remain; after another 5 days, you'd be left with \dfrac{25}4 grams.
