The time required to process a shipment of goods at Wal-Mart varies directly with the number of items in the
shipment and inversely with the number of workers
assigned. If 15,000 items can be processed by 8
workers in 10 hours, then how long would it take 12
workers to process 20,000 items?

a

step-by-step explanation:

strong negative correlation

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

i believe a. 12x≥120 is the answer
