If a and b are positive constants and if a(x-y) = b(y-x), what is the value of the ratio of x/y?

What is the slope simplify your answer and write it as a proper fraction, improper fraction, or integer

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.

Evaluate 8j -k+148j−k+14 when j=0.25j=0.25 and k=1k=1.
