A t-shirt company has initial costs of $1200 per month and it costs them $3.50 per shirt.
Let y represent the cost to run the company each month and x to represent the number of t-shirts
made each month.
a. Find the linear equation that models the costs for the t-shirt company.
b. Write a complete sentence explaining the y-intercept in this application.
c. Write a complete sentence explaining the meaning of the slope in this application.
Answer:
A. y=3.50x+1200
B. the y intercept in this calculation represents the initial cost before producing any t shirts.
C. The slope is representative of the cost per t shirt produced, where x in the equation is the amount of t shirts produced.

What is the design of the following study? The Coca-Cola Company introduced New Coke in 1985. Within three months of this introduction, negative consumer reaction forced Coca-Cola to reintroduce the original formula of Coke as Coca-Cola Classic. Suppose that two years later, in 1987, a marketing research firm in Chicago compared the sales of Coca-Cola Classic, New Coke, and Pepsi in public building vending machines. To do this, the marketing research firm randomly selected 10 public buildings in Chicago having both a Coke machine (selling Coke Classic and New Coke) and a Pepsi machine. The researchers recorded the number of cans sold over a given period of time.
Answer:
Randomized design
Step-by-step explanation:
The researchers used a randomized design for this study. While designing a research experiment, we use a randomized design to study the effect that a major factor or a primary factor would have without having the need to use any unrelated or unnecessary variable. The question tells us that ten public buildings that have a coke machine and a Pepsi machine were selected for the study.
if ta=16 & mh= 18 what is the lenth of mr?
Answer:
the length of MR = 9
Step-by-step explanation:
Looking at the figure, we can tell that segment TR is congruent to segment RA, meaning TR has equal length to RA and the same goes to MR and RH. Since the problem gives us the total length of line TA and line MH, we can say that the length of MR is half of the total length of MH. Therefore, length of MR is 9.

The equation 2(4x + 1) = 4(2x + 5) has no solutions. Which of the following best explains why?
Answer:
See below
Step-by-step explanation:
[tex]2(4x + 1) = 4(2x + 5)[/tex]
[tex]8x + 2 =8x + 20[/tex]
[tex]\nexists x \in \mathbb{R} \text{ That makes the equality true}[/tex]
The equation has no solution because no matter what the value we plug for [tex]x[/tex] in the equation, it will not be true and will lead to a contradiction. This is the meaning of not having a solution.

Answer:
a) y = (x+2)/3
b) 5
Step-by-step explanation:
f^-1(x) means "f inverse of x". To find the inverse, we simply:
a ) f(x) = 3x -2
y = 3x - 2 --> because f(x) is the same thing as y
x = 3y - 2 --> to find the inverse, we simply just switch x and y
x + 2 = 3y
y = (x+2)/3
b) f^-1(13)
f^-1(13) = [((13) + 2)/3]
f^-1(13) = (15)/3
f^-1(13) = 5

1.) A pipe bursts in your house and you call 2 plumbers for estimates. Plumber A says he
charges $40 to check the problem and $ 55 an hour to repair. Plumber B says he
charges $ 60 to check the problem and $ 40 an hour. If the repair takes 4 hours to
complete, which plumber would be a better option.
Answer: Plumber B
Step-by-step explanation:
Plumber A: First, multiply $55 times 4, then add the fee of $40. This will give you $260 as total. This is how much it would cost for Plumber A.
Plumber B: Multiply $40 by 4 and then add $60. This gives you $220, showing that Plumber B is a better option.
Answer:
Plumber B
Step-by-step explanation:
We could set up 2 expressions, and set the time to be 4 hours, and see which plumber costs less:
Plumber A: 40+55*4 = $260
Plumber B: 60+40*4 = $220
Plumber B is cheaper, so therefore he/she is the better option.
144kg in the ratio of 9:8:7
Step-by-step explanation:
Hey there!
Given;
Ratio = 9:8:7
Let "x" be the common factor. So,
9x+8x+7x = 144
or, 24x = 144
or, x = 144/24
or, x= 6
It's like;
= 9*6:8*6:7*6
= 54:48:42
Therefore, their ratio is 54:48:42.

Write the equation of the line through the
points (-8, -2) and (-4,-3) in POINT-SLOPE
FORM
Answer:
Y=-1/4x-4
Step-by-step explanation:
To find the slope, you would need to use the equation y2-y1/x2-x1 by the coordinates. You would get -3-(-2)/-4-(-8). This would result in -1/4. Now that you have your slope, you plug in one of the coordinates. If you used (-8,-2), you would get -2=-8(-1/4)+b. Simplify the equation to get -2=2+b, which simplifies to -4=b, and b is the y intercept.
A job posting is searching for runway models to walk in a designer fashion show. The posting states that the preferred model should be no more than 2 inches away from being 5 feet 11 inches. Write and solve an absolute value inequality that can be used to determine the height range, in inches, of a preferred model. Graph the solution set on a number line.
Answer:
70 ≤ x ≤ 74
Step-by-step explanation:
5 feet 11 inches = (5 x 12 inches) + 11 inches
= 72 inches
Since the preferred model should not be no more than 2 inches away from 72 inches, then;
72 inches ± 2 inches
Let the required height be represented by x, the absolute value inequality is;
lx ± 2l ≤ 72
x + 2 ≤ 72
x ≤ 72 - 2
x ≤ 70
Also,
x - 2 ≤ 72
x ≤ 72 + 2
x ≤ 74
Therefore, the preferred height range in inches is;
70 ≤ x ≤ 74
The graph is herewith attached to this answer.

A recipe calls for 2 1/3 cups of flour, cups of white sugar, and cups of brown sugar. The recipe makes 6 servings.
How many cups of flour are there per serving?
Suppose you modify the recipe to triple the number of servings. How much flour do you need for the modified recipe? [PS]Can you show my how its done too?
Answer:
Lets find how much flour we need for just one serving.
2 2/3 ÷ 6
8/3 ÷ 6
8/3 * 1/6
8/18
4/9 cup of flour per serving
If we triple the recipe (6 * 3 = 18), we will have a total of 18 servings. Multiply the amount of flour we got for one serving to 18 servings.
4/9 * 18/1
72/9
8 cups of flour for 18 servings
