Help ASAP The diagram shows a travel graph for two different cyclists, A and B.
Which cyclist travelled at the greater average speed?

cyclist B is traveling with greater speed. The slope of a distance time graph gives the speed of the object. Here, the slope of cyclist B is greater.

b. astronomers

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
