-6/7

Step-by-step explanation:

x2+5x+6=0

7x+6= 0

   -6    -6

7x= -6

/7    /7

x= -6/7 or -0.85714285714

if your home gets struck by lightning the plan you should create is calling 911 leaving the home wait for athoritys to show up pay hella money for them to put out fire

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."
