Look at these equations. Write each equation in slope-intercept form. Are the equations the same or
different? Explain.
y + 1 = 2x - 3
2x - 3 = y + 1
2y + 2 = 4x - 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.

An arc subtends a central angle measuring 7pi/4 radians what fraction of the circumference is this arc?

The length of an intercepted arc of a central angle of a circle is 4 cm. if the radius of the circle is 5 cm what is the measurement of the central angle to the nearest whole degree
