If r(x) = 3x – 1 and s(x) = 2x + 1, which expression is equivalent to (r/s) (6)?

(a) solve h+2/6 = h-3/4(b) solve the following simultaneous equations. 2x = y + 66x - 2y = 13x = ? y = ?

Which simplifys to a+ b? a-(1-b)+1 -(1-a)-b+1 (a--1) -1)+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.
