Arobin flew rr meters per second, and a cardinal flew cc meters per second. the birds flew for tt seconds. the expression t(r-c)t(r? c) describes how many more meters the robin flew than the cardinal flew during that time. what does (r-c)(r? c) represent in this context?

(r-c)(r?c) represents speed

Step-by-step explanation:

we know formula of distance

s=vt

if we exclude t from it then it remains only speed v

same in the case t(r-c)t(r?c)  when we excludes t

then it remains  (r-c)(r?c) which is equal to speed

hence proved.

the answer is C

Step-by-step explanation:

I got it right on khan

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

d
