Answer:

The intensity of the first earthquake is 6.31 times the second one

Step-by-step explanation:

The given formulae is M=log( $\frac{I}{S}$ )

Here for both the earthquakes the value of S is same.

Let the Intensity of the first earthquake be I1 and the second be I2.

Given M1=7.5

M2=6.7

Now M1=log( $\frac{I1}{S}$ )------1

M2=log( $\frac{I2}{S}$ )-----2

Now subtract 1 and 2 we get

M1-M2=log( $\frac{I1}{I2}$ )

I1/I2= $10^{M1-M2}$

I1=I2( $10^{0.8}$

I1=I2*6.31

Y=3x+13<br> 2x=y-9<br> Solve for x and y points using addition method

GrogVix [38]

$y=3x+13 \\
2x=y-9 \ \ \ |-y-2x \\ \\
y=3x+13 \\
\underline{-y=-2x-9} \ \ \ \hbox{add the sides} \\
y-y=3x-2x+13-9 \\
0=x+4 \\
x=-4 \\ \\
y=3x+13=3 \times (-4)+13=-12+13=1 \\ \\
\boxed{(x,y)=(-4,1)}$
