3. Tom's company needs to hire at least 20 workers. Some of them are working in Factory I (x) for 1000 dollars/month, while others are working in the Factory II (y) for 1200
dollars/month. The total salary of all the workers should be within 30000 dollars. Which
of the following linear inequalities represents the constraints of the given situation?

mk./km: lm

step-by-step explanation:

,mlmlm

; mk

lk

the answer is c just got it on ed

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
