Answer: The required function formula is,
D(t) = 160 - 25 t
Step-by-step explanation:
Given,
The total distance of her from the safe zone = 160 meters,
And, after 3 seconds she is 85 meters far away from the safe zone,
Thus, the total distance she covered in 3 seconds = 160 - 85 = 75 meters,
Since, she drove at a constant speed,
Also,
Thus, the distance she will cover in t seconds = 25 t
( Because, Distance = Speed × Time )
Hence, the total distance of her from the safe zone after t seconds, D(t) = 160 - 25t
Which is the required function formula.
Kayden drives at a constant speed. The function D(t) can be represented as .
Given information:
Kayden is a stunt driver.
Total distance of safe zone is 160 m.
She drove with a constant speed.
After 3 seconds of driving, she was 85 meters away from the safe zone.
So, the distance traveled in 3 seconds will be 160-85=75 m.
Now, the speed of the driver will be,
The distance traveled in t seconds will be 25t.
So, the equation representing the given condition will be,
Therefore, the function D(t) can be represented as .

Answer:
The third choice
Step-by-step explanation:
We need to find the slope and y-intercept of the line and then put it into y = mx = b form. To find the slope, pick a point on the line; I will use (-2, 5); count how many units up you need to go to get to the next point on the line, which in this case it would be 3. The count how many to the right or left you would need to go, which is 1 to the left. Moving left means a negative, so it is -1. Your slope fraction would be , since slope is rise over run. You can sub this fraction in for m in y = mx + b, which will give you a revised equation of y = -3x = b. To find the y intercept, or b, just find the point where the line crosses the y-axis, which is -1. So, the equation is now y = -3x - 1.The correct answer is third choice.

Step-by-step explanation:
He has $500 to start with, and he takes $25 out of the account each week. But he wants more than 200 in his account by the end of summer. 25 goes into 500 20 times. But if he wanted more than 200 left, like 300-400, he could spend 4 week's worth of money to have 400 left, or 8 weeks to have 300 left. This is the best-case scenario.
