The correct answer is 40. Hope that helps!
Answer:
16x <= 80
It's D
16x= 16$ for each hat
80= the most he can spend
In context: Each hat cost 16$ and the most he can spend is 80, nothing more than that.
The simplified polynomial after standard form will be;
⇒ - 8x² - 43x - 36
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The algebraic expression is;
''The expression (3x + 6)² is subtracted from x² - 7x.''
Now,
We can formulate as;
⇒ (x² - 7x) - (3x + 6)²
⇒ x² - 7x - (9x² + 36x + 36)
⇒ x² - 7x - 9x² - 36x - 36
⇒ - 8x² - 43x - 36
Thus, The simplified polynomial after standard form will be;
⇒ - 8x² - 43x - 36

By definition:
- If a system has at least one solution, it's said to be consistent.
- If a system has exactly one solution, it's independent.
- If a system has infinite solutions, it's dependent
- If a system has no solutions, it's inconsistent.
Your system has exactly one solution (the two lines represent the two equations, and the point where they meet is the solution of the system), and so it is consistent, and in particular independent.
