Answer:

Step-by-step explanation:

5(2y + 4) - 11 = 139

5*2y + 5*4 -11 = 139

10y + 20 -11 = 139

10y + 9 = 139         {subtract 9 form both sides}

10y + 9- 9 = 139 -9

10y = 130 {Divide both sides by 10}

10y/10 = 130/10

y = 13

The function​ s(t) represents the position of an object at time t moving along a line. Suppose s (3 )equals 156 and s (6 )equa
bixtya [17]

Answer: The average velocity of the object over the time interval [3,6] is 20.

Step-by-step explanation:

Since we have given that

s(3) = 156

s(6) = 216

We need to find the average velocity over the time interval [3,6].

So, average velocity becomes

\dfrac{s(t_1)-s(t_0)}{t_1-t_0}\\\\=\dfrac{s(6)-s(3)}{6-3}\\\\=\dfrac{216-156}{3}\\\\=\dfrac{60}{3}\\\\=20

Hence, the average velocity of the object over the time interval [3,6] is 20.
