8. 2|x - 7| =-4
What is the solution to this absolute value equation

No solutions

Step-by-step explanation:

2 | x - 7 | = -4       We need to isolate the absolute value, so in order to do that we need to divide 2 from both sides of the equation.

| x - 7 | = -2

Absolute values can not be equal to a negative number.

Therefore, your answer is no solutions.

- "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."

ask the math teacher she or he would know lol.
