Cloud [144]

The swimmer will be 1978.8 m far.

Step-by-step explanation:

The formula to apply here is; speed = distance/time

So in this case, distance =speed * time

Speed = 9.7 m/s

Time = 3.4 minutes ⇒change to seconds, multiplying by 60 sec

Time=3.4×60 = 204 seconds

Distance = 204 × 9.7 = 1978.8 m

Does (-15, -691) make the equation y = -51x - 74 true?

dimulka [17.4K]

Well, we can input both variables to check and see if the numbers hold.

-691 = -51(-15) - 74

-691 = 765-64

-691 = 701

(-15, -691) does not make the equation true.

Answer:

second one

Step-by-step explanation:

Because when you try to remove the brackets then you should multiply coefficient of x and coefficient of y by 2

So it will be 2x+18y
