Answer:

a = 10/3 and b = -196/51.

Step-by-step explanation:

4a + 2b - 12ax + 15b = -40x - 52

Equating coefficients of x:

-12ax = -40x

-12a = -40

a = 40/12

  = 10/3.

Equating constants:

4a + 2b + 15b = -52

4a + 17b = -52

Substituting a = 10/3:

40/3 + 17b = -52

17b = -52 - 40/3

b = (-52 - 40/3) / 17

  = (-156/ 3 - 40/3) / 17

  = -196 / 51

The energy magnitude M of an earthquake can be modeled by the equation
const2013 [10]

Answer: magnitude of an earthquake with an energy release of 7.079 X 10^26 =8

Step-by-step explanation:

Given that the magnitude M of an earthquake can be expressed by the equation

M=(2/3)log E - 9.9

Given that Energy release , E=7.079 X 10^26

Magnotude , M=(2/3)log E - 9.9

=2/3 log7.079 X 10^26 -9.9

2/3 x 2.8499719  -9.9

17.8999813 -9.9

=7.9999

rounded to 8 magnitude
