Answer:
D) 
Step-by-step explanation:
Acceleration is the derivative of velocity, which is the derivative of position, so we must differentiate the function twice:
Position of Particle: 
Velocity of Particle: 
Acceleration of Particle: 
After 
seconds, the acceleration of the particle is 
Answer:
(5, -3)
Step-by-step explanation:
Substitute -2x + 7 for y in the 2nd equation, and then solve the resulting equation for x:
-2x + 7 = 0.5x - 5.5
Combining like terms, 2.5x = 12.5, or x = 5.
Subbing 5 for x in the first equation, we get: y = -2(5) + 7 => y = -3
The solution is (5, -3)
Answer:

Step-by-step explanation:
Answer:
-5/6
Step-by-step explanation:
y2 - y1 / x2 - x1
-6 - 4 / 7 - (-5)
-10 / 12
= -5/6
Answer:
y = 4x + 3
Step-by-step explanation: There are many ways for a Cab company set up its fares. By sure just for have service (get the cab) you must have to be charged, and as is not the same a 4 miles services than a 25 miles services is fare, that a charge should exist asocciated wiht numbers of miles traveled. And certanly this is a typical way companies have.
Company A established a flat free a flat fee for picking a customer in 3 $ and 4$ for each mile or fraction of a mile.
The representation of such arrangement is a straight line. Any of the existing ways to represent a straight line are equaly valid ( if you have two point of the line, or slope and the y axis intercept all are valid. In this example we will use the equation:
y = mx + b (1)
Because is better for us to explain our case.
In a x,y cartesian axes ( y dollars , and x miles ) the two parameters in equation 1, b and m are the intercept of the line with axis y and at the same time a flat fee for get a cab (note x = 0 , you are boarding a cab) and m the slope of the line which the rate of $/miles that customer has to pay.
In our particular case
y = 4x + 3
