The equation d=3t gives the distance, d, in meters that liam swims with respect to time, t, in seconds.
the table gives the different distances in meters that edgar swam with respect to time in seconds.
assume that liam and edgar both swim at a constant rate.
what is the rate of change for each swimmer in term school of meters per second? who swims faster?
label your answer with the name of swimmer

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

22 dimes and 9 nickels

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
