The solutions set to 6+2n> 12 is n> 3. which are correct representations of this solution?

The solution is explained below.

Step-by-step explanation:

Given an inequality

The solution set for above inequality is n>3

we have to write the correct representation of solution for above.

Inequality:

Subtracting 6 from both sides of inequality

Dividing by 2 both sides

which is the required solution set for above inequality.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

- "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."
