Since they take prices rather than setting them, fully competitive enterprises must deal with a completely elastic demand curve.
What is competitive firm?
A perfectly competitive firm is a price taker, which means that it must accept the equilibrium price at which it sells goods. If a perfectly competitive firm attempts to charge even a tiny amount more than the market price, it will be unable to make any sales.
Since they take prices rather than setting them, fully competitive enterprises must deal with a completely elastic demand curve. They are so unable to alter the market selling price. In order to raise its income, a perfectly competitive firm will therefore increase output rather than pricing.
A totally competitive firm is unable to arbitrarily set its output price since it must accept the price set by the product's market demand and supply. As an alternative, the perfectly competitive firm can decide to sell any amount of output for the same price. Because customers are eager to purchase any quantity of the company's output at the market price, it follows that the firm must deal with a completely elastic demand curve for its product. The quantity that the perfectly competitive firm decides to produce, combined with the prices that are in effect on the market for inputs and outputs, will determine the firm's total revenue, total costs, and eventually the level of profits.

If p + q = 11 and 2p + q = 1 it says that 3p + 2q = 12 but I can't understand how they got to the answer. Please can someone explain? Thank you!
The value of p and q in the equation are -10 and 21 respectively.
How to solve system of equation?The value of p and q will be found in the equation before we can form another equation with p and q.
Therefore,
p + q = 11
2p+ q = 1
using elimination method
p = 1 - 11
p = -10
q = 11 + 10
q = 21
Therefore,
3p + 2q = 12 (let's check if its correct)
3(-10) + 2(21) = -30 + 42 = 12

What is the equation of a circle with center (-3, -5) and radius 4?
O A. (x+3)2 + (y + 5)² = 16
O B. (x-3)2 + (y- 5)² = 4
O C. (x+3)2 + (y + 5)² = 4
O D. (x-3)2+(vy- 5)² = 16
The equation of a circle with center (-3, -5) and radius 4 is (x+3)^2+(y+5)^2=16.
In the given equation we have to find the equation of circle with center and radius.
The given center is (-3, -5).
Radius = 4
The standard equation of a circle with center and radius.
(x−a)^2+(y−b)^2=r^2
where a and b represent a point of center and r represent a radius.
So a=-3, b=-5 and r=4.
Putting the value in the standard equation.
(x−(-3))^2+(y−(-5))^2=(4)^2
Simplifying
(x+3)^2+(y+5)^2=16
Hence, the equation of a circle with center (-3, -5) and radius 4 is (x+3)^2+(y+5)^2=16.

Answer:
(2, 2 )
Step-by-step explanation:
2y + x = 6 → (1)
2y - 3x = - 2 → (2)
subtract (2) from (1) term by term to eliminate y
(2y - 2y) + x - (- 3x) = 6 - (- 2) , that is
x + 3x = 6 + 2
4x = 8 ( divide both sides by 4 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (1)
2y + 2 = 6 ( subtract 2 from both sides )
2y = 4 ( divide both sides by 2 )
y = 2
solution is (2, 2 )

y-3=-10(x-2) This equation is in point-slope form so the slope is -10
The perpendicular slope is the negative reciprocal so 1/10.
Slope intercept form is y=mx+b
Plug in the points of the x-intercept and slope into y=mx+b

Ann starts to translate the document.
After 2 days Ann and Ben both work on translating the documents.
How many more days will it take to complete the work?
They would require more 4 8/22 days to complete the work.
Ann can translate the document in 10days
In 1 day he can translate 1/10 of the document
In 2 days he translates = 2 x 1/10
Ben can translate the same document in 12 days
In 1 day he can translate 1/12

If x represents the cost of each bag of oranges then the equation will be 7x+5.65 = 34.07 and the value of x is $4.06.
According to the question,
We have the following information:
Alexander buys ice cream and oranges at the store.
• He pays a total of $34.07.
• He pays $5.65 for the ice cream.
• He buys 7 bags of oranges that each cost the same amount.
Let's take the cost of each bag of oranges to be $x.
We have the following equation:
7x+5.65 = 34.07
Subtracting 5.65 from both sides:
7x = 34.07-5.65
7x = 28.42
x = 28.42/7

= x(x² - 2x - 24) ← factor the quadratic
consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 2)
the factors are - 6 and + 4 , then

Also, it was further stated that the tour group consists of m nonsenior adults, (5/4m +6) children, and 8n senior citizens.
The total amount for the fees will be:
= Non senior adults + Children + Senior citizen
= 12.5(m) + 8(1.25m + 6) + 6.50(8n)
= 12.5m + 10m + 48 + 51n
= 22.5m + 48 + 51n
= 22.5m + 51n + 48

What is the equation of the function
The equation of line will be given as y = 3x + 24
Given,
The graph of a linear function passes through the points (4, 24) and (6, 30).
The equation of the line will be given as:-
y - y₁ = m ( x - x₁)
Slope m will be calculated as:-
m = (y₂ - y₁) / (x₂ - x₁) = (30 - 24) / (6 - 4) = 6/2 = 3
The equation will be:-
y - 24 = 3 ( x - 4 )
y = 3x - 12 + 24
y = 3x + 24
Therefore the equation of the line will be given as y = 3x + 24.

if 4 points are indicated on a line and 5 points are indicated on another line that is parallel to the first line, how many triangles can be formed whose vertices are among the 9 points?
There are 19 triangels can be formed whose vertices are among the 9 points.
A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees. It means that the sum of the interior angles of a triangle is equal to 180°. It is a polygon having the least number of sides. In other words, a triangle is defined as a three-sided two-dimensional figure whose interior angles are equal to 180°.
In geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet. They can be both horizontal and vertical.
From the question, we know that we have 9 point from 2 line parallel. There are 19 triangels (the same shape is not counted twice) can be formed whose vertices are among the 9 points that shown in the following picture.
