What is the change in elevation between 8,500m and -300m

Suppose the equation ||x-a|-b|=2008 has 3 distinct real roots and a not =0. find the value of b.

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.

Find the slope of the line that passes through the points (0, 0) and (-2, -3). 2/3 3/2 -3/2
