A student has a business selling snowballs during the summer. For each snowball the student sells, they makes a profit of $1.50. On the hottest day of the summer, the student sold 125 snowballs and made a profit of $187.50.Choose a model (equation) in point-slope form {y−y1=m(x−x1)} to represent the profit the student makes, y, based on the number of snowballs sold, x.y−125=1.5(x−187.5) Ay+187.5=1.5(x+125) By−187.5=1.5(x−125) Cy+125=1.5(x+187.5) D

The difference between the polynomials 5x² + 2x + 11 and 7 + 4x - 2x² is 7x² - 2x + 4 option (D)7x² - 2x + 4 is correct.
What is polynomial?
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
The complete question is:
FIND THE DIFFERENCE:
(5x² + 2x + 11) - (7 + 4x - 2x²)
- A. 9 - 2x - 2x²
- B. 3x² - 2x + 4
- C. 3x² + 6x + 4
- D.7x² - 2x + 4
We have two polynomials:
5x² + 2x + 11 and 7 + 4x - 2x²
We have subtract the polynomial 7 + 4x - 2x² from the polynomial 5x² + 2x + 11
= (5x² + 2x + 11) - (7 + 4x - 2x²)
Using distributive property:
= 5x² + 2x + 11 - 7 - 4x + 2x²
= 7x² - 2x + 4
The difference is 7x² - 2x + 4
Thus, the difference between the polynomials 5x² + 2x + 11 and 7 + 4x - 2x² is 7x² - 2x + 4 option (D)7x² - 2x + 4 is correct.

Answer:
(-2, -2)
Step-by-step explanation:
Compare the two functions ...
f(x) = -|x +2| -2
f(x) = a·g(x -h) +k
where f(x) is a translation and scaling of function g(x). Here, you have ...
g(x) = |x|
The scale factor is a = -1.
The horizontal shift is h = -2.
The vertical shift is k = -2.
_____
The original vertex at (0, 0) has been shifted by (h, k) to ...
(0, 0) + (h, k) = (0, 0) + (-2, -2) = (-2, -2).
