Write an equation of the line that passes through (7,10) and is perpendicular to the line y=1/2x-9

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.

Common binomial factor of 6x(3x+7)+5(3x+7)

What is the t intercept of the line given by the equation below y= -10x + 14
