I will give brainliest Answer two questions about equations A and B:

A. x/4+1=-3

B. x+4=-12

1) how can we get equation B from equation A?

choose 1

(Choice A) rewrite one side (or both) using the distributive property

(Choice B) rewrite one side (or both) by combining like terms

(Choice C) multiply/divide only one side by a non zero constant

(Choice D) multiply/divide both sides by the same non zero constant

2) based on the previous answer ,are the equations equivalent? in other words ,do they have the same solution?

choose 1

(Choice A) yes

(Choice B) no

a

explanation:

it's both, now can you answer my most recent question?

- "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."
