Solve the following lp problem graphically by enumerating the corner points. hint: find all the corner points and plug those values in the objective function then take the largest value - to find the corner points, you need to find the intersection of two lines solving simultaneously. max: 3x1 + 4x2 subject to: x1 ≤ 12 x2≤ 10 4x1 + 6x2 ≤ 72 x1, x2 ≥ 0

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

it is c, trust i got your back lol

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."
