2) 5x2 – 3x + 7x2 - 4x + 9

3) 2(x + 4) + 3(x – 5) – 2y

4) – 7(x - 1) + 5(2x + 3)

5) 3y – 12 – 1(y + 1)

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
