Let's solve the logarithmic equation log(3) + log(x − 4) = log(x). (a) First, we combine the logarithms on the LHS to get the equivalent equation = log(x). (b) Next, we use the fact that log is one-to-one to get the equivalent equation = x. (c) Now we find x = .

i really do not know lamo this is great

- "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."
