To write the function correctly, it is important to assign variables correctly and understand the situation of the problem clearly. For this, we let y the number of people and x as the number of songs played.
At x = 0 y = 567
at x = 1 y = 567 - 567(1/3)
at x = 2 y = 567 - 567(1/3)(1/3)
at x = 3 y = 567 - 567(1/3)(1/3)(1/3)
Therefore, the number of people left after x songs would be represented by the equation:
y = 567 - 567(1/3)x
y = 567 ( 1- x/3 )
Answer:
Option C is correct.
Step-by-step explanation:
We have been given that Kelly wants to create a rectangular playpen for his cats backyard
And cats need 500 square feet
And length of playpen to be 20 feet longer than the width.
Let the width of playpen be x.
Then the length of playpen be (x+20).
Then the equation becomes:
x(x+20) =500
We will solve above for x.
Using discriminant
Now, we will use formula for x which is:
Taking 2 as common factor from numerator and denominator.
Or
Option c is correct.
