Solve for x and show your work! For each equation choose if there are: • zero solutions for x • exactly one solution for x • or an infinite number of solutions for x.

2(3x + 9) = 18 + 6x

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

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.

The formula for the lateral area of a right cone is la = rs, where r is the radius of the base and s is the slant height of the cone.which are equivalent equations?
