the answer would be d because it goes down 2 and over 1
The complete question implies that we define an inequality that represents the relationship between the number of hours worked in a week and the weekly sales
The inequality that relates the number of hours to the weekly sales is:
We make use of the following representation:
weekly sales from cars.
hours worked in a week
His weekly salary is then calculated as:
Salary (S) = Earnings per week + Commission * Sales from car
So, we have:
Express percentage as decimal
Assume he works for y hours in a week.
His hourly rate is:
--- i.e. weekly salary divided by number of hours
For this rate to be at least 
, the following condition must be true
--- i.e. is hourly rate must be greater than or equal 35
So, we have:
Multiply both sides by y
So whenever a problem says "of" a value, multiply.
24 * 1/3 = 24/3 = 8

Answer:
670 616 629 miles per hour?
Step-by-step explanation:
Answer:
I. m = 2401
II. ((n+1) ∆ y)/n = 1/n[(n – y + 2)(n – y) + 1]
Step-by-step explanation:
I. Determination of m
x ∆ y = x² − 2xy + y²
2 ∆ − 5 = √m
2² − 2(2 × –5) + (–5)² = √m
4 – 2(–10) + 25 = √m
4 + 20 + 25 = √m
49 = √m
Take the square of both side
49² = m
2401 = m
m = 2401
II. Simplify ((n+1) ∆ y)/n
We'll begin by obtaining (n+1) ∆ y. This can be obtained as follow:
x ∆ y = x² − 2xy + y²
(n+1) ∆ y = (n+1)² – 2(n+1)y + y²
(n+1) ∆ y = n² + 2n + 1 – 2ny – 2y + y²
(n+1) ∆ y = n² + 2n – 2ny – 2y + y² + 1
(n+1) ∆ y = n² – 2ny + y² + 2n – 2y + 1
(n+1) ∆ y = n² – ny – ny + y² + 2n – 2y + 1
(n+1) ∆ y = n(n – y) – y(n – y) + 2(n – y) + 1
(n+1) ∆ y = (n – y + 2)(n – y) + 1
((n+1) ∆ y)/n = [(n – y + 2)(n – y) + 1] / n
((n+1) ∆ y)/n = 1/n[(n – y + 2)(n – y) + 1]
