Answer:
The point (-4,5) is on the line
Step-by-step explanation:
You can replace the x and y values to determine if it is a true statement
First Statement
5= 2(-4)+13 -> 5= -8+13 -> 5=5 true
Second Statement
-4=2(5)+13 -> -4= 10+13 -> -4 ≠ 23 false
You can automatically eliminate the next two answers because you already found that the first statement is true and because you can find points using an equation.
The best answer would be B.
The numbers divided are the closest to the original decimals.
Hope this helps!
The Richter Scale calculates earthquake intensity on a logarithmic scale.
So, a magnitude 6 earthquake has 10 times the energy of a magnitude 5 earthquake.
The difference between 6.9 and 5.4 is 1.5 and so the difference in intensity is 10^1.5 or about 31.62.
