Answer:
He sold a total of 37 albums last month.
Step-by-step explanation:
Given,
Total earned money = $644
Base payment = $200
Additional payment for each album = $12
We have to find the number of albums sold by him.
Solution,
Let the number of albums be 'a'.
Total earned money is the sum of base payment and additional payment for each album multiplied with number of albums sold.
So framing in equation form, we get;
Subtracting both side by '200' using subtraction property, we get;
Now dividing both side by '12' using division property, we get;
Hence he sold a total of 37 albums last month.
PART A:
The x-intercept at 0 shows the location where the ball was kicked. The x-intercept at x = 16 shows the location where the ball hit the ground.
The maximum value represents the highest point of the ball.
The interval where the function is increasing is 0<x<8. Between this interval, the height of the ball measured from the ground is increasing.
The interval where the function is decreasing is 0<x<16. Between this interval, the height of the ball is decreasing.
PART B:
Reading from the graph
When x = 8, y = 10 ⇒ let this be x₁ = 8 and y₁ = 10
When x = 13, y = 6 ⇒ let this be x₂ = 13 and y₂ = 6
The rate of change = (y₂-y₁) / (x₂-x₁)
The rate of change = (6 - 10) / (13 - 8)
The rate of change = -4 / 5 = -(4/5)
Answer: The answer is 60 min.

The coefficients are 2 and -3
The exponents are 5 and 1
Step-by-step explanation:
Given
Required
The coefficient and exponent
First, identify the terms.
The terms are: 
and 
The coefficient are the numbers written before the variables
The exponents are the power of the variables
So; for :
For
For this case we must find the quotient of the following expression:
We can rewrite the expression as:
By definition of division of powers of the same base, we place the same base and subtract the exponents:
So:
