From examining the graph in the "image attached", note that we have a "line" in linear format" ; and that has a "solid line" (as opposed to a "dashed line"); with a "shaded portion" toward one side.
The presence of a "solid line" indicates:
" ≥" {"greater than or equal to"} ; or,
" ≤ " {"less than or equal to"};
________________________________________________________
So we can narrow down our answer choices to:
________________________________________________________
[C]: " y ≤ x − 2 " ; and:
[D]: " y ≥ x − 2 " .
________________________________________________________
Note:
________________________________________________________
A "dashed line" would have narrowed our answers to Choices [A] & [B].
_______________________________________________________
Now, look at inequalities in choices [C] & [D].
Start with Choice: [C]: " y ≤ x − 2 " ;
Now, take the point in the graph: "(0, 0)" ; which is in the shaded portion.
That is; when "x = 0 ; y = 0" .
Does this hold true for the inequality provided for Choice [C]:
→ " y ≤ x − 2 " ?
→ Plug in "0" for "x" ; and "0" for "y" ; and see if the inequality holds true ;
→ " 0 ≤ 0 − 2 " ?
→ " 0 ≤ -2 " ?? No!
_________________________________________________________
As such, the correct answer is: Answer choice: [D]: " y ≥ x − 2 " .
_________________________________________________________
However, let us substitute: x = 0 ; y = 0 ; for the point: " (0, 0)" within the "shaded portion" of the graph; as done above ; but this time, use the inequality for "Choice: [D]: " y ≥ x − 2 " .
→ " 0 ≥ 0 − 2 " ? ;
→ " 0 ≥ -2 " ?? Yes!
________________________________________________________
The correct answer is: [D]: " y ≥ x − 2 " .

Answers
Answer: [tex]24\pi\text{ units}^2[/tex]
Step-by-step explanation:
We know that the total surface area of a cylinder is given by :-
[tex]TSA= 2\pi r(r+h)[/tex] , where r = radius and h= height of cylinder.
Given : Height : h= 4 units
Radius = 2 units

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
What is the slope of the function representing the weekly paycheck amount for Salesman A? Use complete sentences to explain your reasoning, or show your calculations.
What is the slope of the function representing the weekly paycheck amount for Salesman B? Use complete sentences to explain your reasoning, or show your calculations.
What is the slope of the function representing the weekly paycheck amount for Salesman C? Use complete sentences to explain your reasoning, or show your calculations.
Answers
He earns $65 per sale, with a maximum weekly commission of $1,300.
=> p(s) = 65s / p ≤ $1,300. This is the paycheck (p) equal 65 times the number of sales s, with an upper bound of $1,300.
The slope of the function is the coefficient of the the indepent variable s, this is 65.
The slope is the rate of change on the paycheck per unit of sales done (s).
Answer: slope 65.
2) Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale.
p(s) = $300 + 40s
The slope is 40 (the coefficient of the independent variable).
Again, the slope is the increase in the paycheck per unit of sale (s) performed.
Answer: slope = 40
3) Salesman C does not earn any commission. His weekly salary is $900.
p(s) = $900
It turns out that really the paycheck of this salesman is not a function of the number of sales. His/her paycheck is constant. That means that the paycheck does not change with the number of sales, and so the slope is 0.
The function is a horizontal line (slope 0).
Answer: slope 0
Final answer:
Slope of function for Salesman A: 65
Slope of function for Salesman B: 40
Slope of function for Salesman C: 0
Explanation:
Slope of function for Salesman A: The slope of the function representing Salesman A's weekly paycheck is $65 per sale, as he earns $65 per sale. Since the commission is a constant rate per sale, the slope remains constant.
Slope of function for Salesman B: The slope of the function representing Salesman B's weekly paycheck is $40 per sale. This is because he earns $40 per sale, which makes the slope $40.
Slope of function for Salesman C: The slope of the function representing Salesman C's weekly paycheck is 0. Salesman C does not earn any commission, so his weekly salary remains constant at $900, regardless of the number of sales made.

x = 5/30.9 of Karen's Science score is equal to 0.75 of her Math score and 0.8 of her Chemistry score. Given that Karen scored 96 marks for her Math, what was her total score of the 3 subjects?
Answers
You have to formulate equations for this problem.
Let S = Science score
M = Math score
C = Chemistry score
To illustrate the given:
0.9S = 0.75M
0.9S = 0.8C
You are given that Karen’s Math score is 96 marks. You have to substitute the Math score to the first equation.
0.9S = 0.75(96)
0.9S = 72
S = 80
Therefore, Karen’s Science score is 80. Now, you have to substitute the Science score to the second equation.
0.9(80) = 0.8C
0.8C = 72
C = 90
So, Karen’s Chemistry score is 90.
Therefore, the total score of the 3 subjects is 266 (96 + 80 + 90).

if ABC and GEF are congruent by the ASA criterion, which pair of angles must be congruent
Answers
The pair of angles that must be congruent for the given pair of congruent triangles are ∠CAB and ∠GEF.
The ASA criterion states that two triangles are congruent if two angles and the included side of one triangle are equal to the two angles and the included side of the other triangle.
In the figure, we have:
∠ABC = ∠GEF (given)
∠ACB = ∠EGF (included angles)
AC = EG (included side)
Therefore, by the ASA criterion, triangles ABC and GEF are congruent.
The other possible pairs of congruent angles are:
∠ACB and ∠FEG
∠CAB and ∠EGF
∠ABC and ∠GFE
However, none of these pairs of angles are included angles.
Therefore, the only pair of congruent angles that must be congruent is ∠CAB and ∠GEF.

For the solution of this question we will use a technique called the Unitary Method. In this method we find the value of a single unit, which is 1, and then finding the necessary value by multiplying the single unit value.
In our case we are already given the value of the single unit which is 1 inch. And it is also given in the question that 1 inch = 50 miles. Thus, to find the value in miles 2.6 inches, all that we have to do multiply the single unit value, which is 50 miles, with the value given which is 2.6 inches.
Thus, we have:
If 1 inch represents 50 miles,
then 2.6 inches represents [tex] 2.6\times 50 [/tex] miles=130 miles
Thus, 130 miles is the correct answer.

1. (a) Yared will still need to finish wrapping 4 presents when Luke finished wrapping all of his own presents.
Yared takes 15 minutes to wrap 3 presents, and Luke takes 20 minutes to wrap 5 presents.
I divided 15 by 3 to get 5, and did the same with Luke, and I got 4. Both boys have a total amount of 20 presents to wrap, so I multiplied 5 by 20, to get 100, and I multiplied 4 by 20, and got 80.
I subtracted 100 by 80, and got a 20. Since I am finding information for Yared, I’m going to use 5, I divided 20 by 5, and got 4.
(b) Yared still needs to wrap 20% of his presents when Luke has finished wrapping presents.
Since the total amount of
presents to wrap is 20, I divided that by the total amount of presents that
Yared still needs to finish wrapping, which is 4. 4 divided by 20 is 0.2, and I
multiplied 0.2 by 100, 100 is the whole, and I got 20.
2. (a) 50 people said their favorite color was red.
Since there is 250 people in total, I used the percentage of the color red, which is 20%, and multiply it by 250. 20 divided by 100 is 0.2, and I multiply 0.2 by 250, which got me 50.(b) 20 more people said their favorite vehicle color was blue compared to those who said white. I used the same formula as (a). The percentage of blue is 32%, so I divided 32% by 100, and I got 0.32. I multiplied the total amount of people, which is 250, by 0.32, and I got 80. The total amount of people who said they liked blue is 80. The percentage of people who said they like white is 24%, so I divided 24% by 100, and I got 0.24. I multiplied that to 250, and got 60. The total amount of people who said they liked white is 60. I subtracted 80 to 20, to get 20.
(c) 45 people said their favorite vehicle color was black. I divided 18 by 100, and got 0.18. I multiplied 0.18 by 250. I got 45.
