The number line shows the distance in meters of two skydivers, A and B, from a third skydiver located at point X:

A horizontal number line extends from negative 3 to positive 3. The point labeled as A is at negative 2.5, the point 0 is labeled as X, and the point labeled B is at 0.5.

Write an expression using subtraction to find the distance between skydivers A and B. (5 points)

Show your work and solve for the distance using additive inverses. (5 points)

Answer:B ≥ 0.5 – A ≤ -2.5 = -3 is ( 0.5x ) – ( -2.5x) = -3xStep-by-step explanation:A and B= 2 skydiver’s distanceeach from x = -2.5 and 0.5 inequality shows us when x = 0 then A ≤ -2.5 The second inequality shows us when x = 0 then B ≥ 0.5 here on number line we an keep closed circles and shaded lines in opposite direction each from 0 showing domain is x domain = -2.5 to 0 and x domain = 0 to 5 (using commas instead of to) The actual expression then goes B ≥ 0.5 – A ≤ -2.5 = -3 so we an just use ( 0.5x ) – ( -2.5x) = -3x
