N is -4
6n + 9 =  - 3n - 21 - 6 \\ 9n =  - 36 \\ n =  \frac{ - 36}{9}  =  - 4

Answer:

n=-4

Step-by-step explanation:

6n + 9 = -3n - 21 - 6

Add 3n to each side

6n+3n + 9 = -3n+3n - 21 - 6

9n+9 = -27

Subtract 9 from each side

9n+9-9 = -27-9

9n = -36

Divide each side by 9

9n/9 = -36/9

n = -4

A race car driving under the caution flag at 40 feet per second begins to accelerate at a constant rate after the warning flag.
shtirl [24]

Answer:

t = 1.667 s

Step-by-step explanation

The distance traveled since the warning flag in feet is characterized by

d = 30*t^2 + 40*t

Where t is the time in seconds after the car starts accelerating.

We can easily solve this question by plotting the equation using a graphing calculator or plotting tool.

We need to find the time for which the distance d = 150 ft

150 = 30*t^2 + 40*t     , t > =0

We can see that this value in the graph is approximately

t = 1.667 s

We can verify

30*(1.667)^2 + 40*(1.667 ) ≈ 150
