A jewelry artist is selling necklaces at an art fair. It costs $135 to rent a booth at the fair. The cost of materials for each necklace is $4.50. The artist is selling the necklaces at $12 each. The inequality LaTeX: 12n > 135 + 4.50n12 n > 135 + 4.50 n represents the situation in which the artist makes a profit. Will the artist make a profit if she sells 15 necklaces? Show how you know. Be sure to indicate what the variable n represents.
Answer:
The artist will make a profit if she sells 15 necklaces. This is known because 15 is greater than 11.625 (i.e. 15 > 11.625).
Step-by-step explanation:
Note: The question contains some error. The question is therefore rewritten before is answered as follows:
A jewelry artist is selling necklace at an art fair. It costs $135 to rent a booth at the fair. The cost of material for each necklace is $4.50. The artist is selling the necklace at $12 each. The inequality 12n>135+4.50 represents the situation in which the art is making the profit. Will the artist make a profit if she sells 15 necklaces? Show how you know. Be sure to indicate what the variable n represents.
The explanation of the answer is therefore given as follows:
Given;
12n > 135 + 4.50 .................... (1)
Where n represents the number of necklace that must be sold by the artist to make a profit.
Solving for n from equation, we have:
12n > 139.50
n > 139.50 / 12
n > 11.625 ..................... (2)
Equation (2) implies that more than 11.625 necklaces must be sold by the artist to make a profit.
When the artist sells 15 necklaces, it implies that n = 15.
Since more than 11.625 necklaces must be sold by the artist to make a profit, it therefore implies that the artist will make a profit if she sells 15 necklaces. This is known because 15 is greater than 11.625 (i.e. 15 > 11.625).
Pleaz Helpz!!! I needz this done before my final!!!
the perimeter of the field is 442
width=w
the length of the field is 9 yards less than quadruple W
L=4x - 9
the perimeter is P=2L+2W
you can plug in the values
P= 2(4w-9) + 2W
plug in 442 for P
442= 2(4w- 9) + 2W
442= 8w - 36 + 2W
478 =8w + 2W
478= 10W

An online clothing company sells custom sweatshirts. The company charges $ for shipping plus $ for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Complete question :
An online clothing company sells custom sweatshirts. The company charges $4.99 for shipping plus $7.50 for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Answer:
y = 7.50x + 4.99
Step-by-step explanation:
Given that :
Shipping fee = 4.99
Cost per shirt = 7.50
Writing the relation in the form of a linear equation :
General form of a linear function :
y = mx + c
Where m = slope ; c = intercept
The total cost of ordering x sweatshirts :
y = (cost per sweatshirt * number ordered) + shipping fee
y = 7.50x + 4.99
Answer:
the answer is $7.99

how are ASA and AAS used to show that triangles are congruent?
Answer:
If two pairs of corresponding angles and the side between them are known to be congruent, the triangles are congruent. This shortcut is known as angle-side-angle (ASA). Another shortcut is angle-angle-side (AAS), where two pairs of angles and the non-included side are known to be congruent.
In ASA, two angles and one common side is equal and in AAS one not common side and two angles are equal.
What is triangle?Simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes is represented by the symbol and consists of three connected vertices.
The ASA congruence means, there will be two corresponding angles and one side between them will be equal, then the triangles are congruent.
The AAS congruence means, there will be two corresponding angles and one side excluded from them will be equal, then the triangles are congruent.

WILL GIVE BRAINLIEST
Answer:
y=2x−1
Explanation:
First, we need to determine the slope of the line. The formula for determining the slope of a line is:
m=y2−y1x2−x1
where m is the slope and the x and y terms are for the points:
(x1,y1) and (x2,y2)
For this problem the slope is:
m=3−−12−0
m=3+12m=42m=2
Now, selecting one of the points we can use the point slope formula to find the equation.
The point slope formula is:
y−y 1=m(x−x1)
Substituting one of our points gives:
y−1=2(x−0)y+1=2x
Solving for y
to put this in standard form gives:
y+1−1=2x−1
y+0=2x−1
y=2x−1

Answer:
6x - 20y
Step-by-step explanation:
This is the answer because:
1) Factor the numerator and denominator and cancel the common factors.
2) Multiply the -3 to everything inside the parenthesis:
−2[−3x − 6y + 4y]
3) Then, multiply the -2 with all the numbers:
6x - 12y + 8y
4) Finally, combine all the like terms:
6x - 20y

The slope of the given line is -4
Step-by-step explanation:
The formula of the slope of a line passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]
In the given figure
∵ The line passes through the points (-6, 5) and (-4, -3)
∴ x1 = -6 and y1 = 5
∴ x2 = -4 and y2 = -3
→ Substitute them in the formula of the slope above
∵ m = [tex]\frac{-3-5}{-4--6}[/tex]
∴ m = [tex]\frac{-8}{-4+6}[/tex]
∴ m = [tex]\frac{-8}{2}[/tex]
∴ m = -4
∴ The slope of the given line is -4
