4m² – 3m6 – 5m4
What is the degree of the polynomial?

Use the elimination method to find the solution to the system of equations. 2x - 3y = -9 -x + 3y = 6

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.

Ineed with number 6 , explain how to get 1978
