Show that the equation y + 2 = 2(2x + 1) is linear and that it represents a proportional relationship between x and y.

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.

Which expression gives you the distance between the points (5,1)and(9,-6)

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
