I think
y = 3x - 9x + 3x - 2
y = - 3x - 2
Answer:
Multiply by -2
Step-by-step explanation:
Additive inverse essentially means the counterpart that negates a number. Then, elimination can be used. In this case, the easiest change would be with the terms -4y in the first equation, and -2y in the second equation, since 2 is a factor of 4. So,
3x - 4y = -5
5x - 2y = -6
The goal here is to cancel out the -4y.
(5x - 2y)(-2) = (-6)(-2)
-10 + 4y = 12
3x - 4y = -5
Now it works.
Divide off -3 from both sides, that leave you with:
n + 5 = -4
Subtract the 5 to the other side
n = -9

Hello!</h2>
The answer is: 4.0 (at Richter scale)
<h2>Why?</h2>
The answer is 4.0 Assuming the standard earthquake as 1.0 (at Richter scale).
An earthquake of 1.0 at Richter scale is equal to:
An earquake of 2.0 at Richter scale is equal to:
and so...
Therefore,
An earthquake of 4.0 at the Richter scale is equal to:
So, it means that an earthquake with 4.0 magnitude at the Richter scale is 10000 times more intense than a standard earthquake, assuming it as 1.0 at Richter scale magnitude.
Have a nice day!
