Answer:
<h2>1</h2>
Step-by-step explanation:
Magnitude 
of an earthquake is defined as 
. Here 
is the Intensity of the earthquake and 
is the intensity of standard earthquake.
We have an earthquake that is 10 times more intense than a standard earthquake. Let us denote the intensity of the earthquake as .
10 times more intense than standard earthquake ⇒ 
Magnitude of the earthquake = 
∴ Magnitude of the earthquake is 1.
Answer:
The two numbers are 5 and 1. Their product is 5
Step-by-step explanation:
x + y = 6 (*)
x - y = 4 (**)
Let (*) + (**)
--> (x+y) + (x-y) = 6 + 4
<=> 2x = 10 <=> x = 5
Substitute x= 5
(*) <=> 5 + y = 6
<=> y=1
Answer: (x,y) = (5,1)
Their product: x.y = 5x1 = 5
Answer:
What's the purpose? ................
y=-4-x
y=2x-1
-4-x=2x-1
3x=-3
x=-1
y=-3
The type of equation is consistent because they intersect at ( -1,-3 )
