Using linear functions, it is found that:
A. The costs will be the same when 250 shirts are bought.
B. The Tees-4-U Company would charge them less.
C. They are saving $350 by going with the more economical company.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For the cost functions in the context of this problem, we have that:
The slope represents the cost per shirt.The intercept represents the flat fee.Hence the functions for the cost of buying x shirts are given as follows:
Custom Ink: C(x) = 6.5x.Tees-4-U: T(x) = 250 + 5.5x.The costs will be the same when:
C(x) = T(x)
Hence:
6.5x = 250 + 5.5x
x = 250
For item b, the costs are given as follows:
C(250) = 6.5(600) = 3900.T(250) = 5.5(600) + 250 = 3550.The amount saved in item c is:
3900 - 3550 = 350.

cual es el valor absoluto de -x+2
The absolute value of -x+2 is 2-|x-2|.
What is the Absolute Value ?
The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is indicated by the symbol |x|.
Since the absolute value is isolated, we set it equal to the positive and negative of the constant
Therefore,
|(-x+2)| =
for x < 2, -(-x + 2)
for x ≥ 2, (x + 2)
Hence, This is so that no matter the value of x, the value of the function is always greater or equal to 0.

A packet of carrot seeds has a germination rate of 92%. In other words, the probability of any
seed sprouting is 0.92. How many seedlings would you expect in a row of 50 seeds?
The number of constructive seedlings in a row of 50 seeds is 46.
What is probability of a given event and how can it be analyzed?
Potential is described by probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability generally refers to the degree to which something is likely to occur. Utilize probability to ascertain how likely something is to occur. Many things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty. Every event's probability in a sample space is one.
Given, the germination rate of the seeds to seedlings is = 92%
Therefore, the probability of any seed sprouting is 0.92.
Hence the required number of seedlings can be expected in a row of 50 seeds = 50*0.92 = 46 seeds
Thus, the number of constructive seedlings in a row of 50 seeds is 46.

Roland's farm land is assessed at 1.5 million dollars and the improvements for $500,000.
At a tax rate of 4 mills, how much are Rolan's monthly taxes?
At a tax rate of 4 mills, Rolan's monthly taxes are $667.00.
What is the mill rate?The amount of tax due per $1 of a property's assessed value is known as the mill rate. The word mill comes from the Latin millesimum, which means thousandth. In terms of property tax, 1 mill is the amount of property tax levied per $1,000 of the assessed value of a property. Divide the mill rate by 1,000 and multiply the assessed value of the property to determine the property tax.Given:
Assessed value = 1.5 million dollars
Amount for Improvements = $500,000
Tax rate = 4 mills
Total assessment of the property = Assessed value + Improvements
= 1,500,000 + 500,000
= $2,000,000
Multiply these 2 million by 4 mills then divide by 1000.
(2,000,000 × 4)/1000
= $8000 in annual taxes
To calculate the monthly tax amount divide by 12.
$8000/12 = $667.00

To add mixed numbers first, we can add the whole numbers:
[tex]7+4=11[/tex]Now, we can add the fractions. For this, we can find the lowest common denominator (LCD) of both denominators. The LCD is the lowest number that is evenly divisible by both numbers. Since the denominators of the fractions are 10 and 15, the LCD is 30 because 30 is the smallest number that is divisible by 10 and 15. Then, we have:
[tex]\begin{gathered} \frac{3}{10}+\frac{4}{15}=\frac{3\cdot3}{10\cdot3}+\frac{4\cdot2}{15\cdot2} \\ \frac{3}{10}+\frac{4}{15}=\frac{9}{30}+\frac{8}{30} \\ \frac{3}{10}+\frac{4}{15}=\frac{9+8}{30} \\ \frac{3}{10}+\frac{4}{15}=\frac{17}{30} \end{gathered}[/tex]Therefore, the result of adding the given mixed numbers is:

Step-by-step explanation:
Factor completely the trinomial 10x^2 + 19x + 7
From the problem :
[tex]10x^2+19x+7[/tex]Factor completely :
We need to find the factors of 10 and 7
We have :
10 = 1 x 10
10 = 2 x 5
7 = 1 x 7
We will do trial and error, The sum of the product of the factors must be equal to the middle term which is 19
Let's say for 10 = 1 x 10 and 7 = 1 x 7
(1 x 7) + (1 x 10) = 17 not equal to 19
(7 x 10) + (1 x 1) = 71 not equal to 19
try the other factors of 10.
10 = 2 x 5 and 7 = 1 x 7
(2 x 7) + (5 x 1) = 19 Equal to 19
Now we have the factors, let's arrange in this way :
[tex](O+I)(I+O)[/tex]O will be the outer and I will be the inner.
O is the paired factors of 10 and 7
For O, we have 2 and 7
For I, we have 5 and 1
This will be :
[tex](2x+5)(x+7)[/tex]The answer is (2x + 5)(x + 7)

What is normal probability distribution?
Normal distribution also known as the Gaussian probability, ia a probability distribution that is symmetric about the mean, showing that data bear the mean are more frequent in occurrence than data far from the mean.
In a set with mean μ and standard deviation (which is the square root of the variance) σ , the z score of a measure X is given by:
Z =X-μ/σ
we have given μ =129
σ = [tex]\sqrt{100}[/tex] n = 96
This is the pvalue of Z when X = 129+1.7 =130.7 subtracted by the pvalue of Z when X = 129 - 1.7 = 127.3
When X = 130.7
Z =X-μ/σ
Z = 130.7-129/10
Z = 0.17 pvalue = 0.1699
When X = 127.3
Z =X-μ/σ
Z = 127.3-129/10
=-0.17 pvalue
0.1699 - 0.1700 = -0.001
Hence the probability is -0.001

Jan made a mixed vegetable soup using tomatoes and carrots. Forty percent of the
tomatoes. If she used a total of 50 tomatoes, how many carrots should she use?
Jan should use 75 carrots for mixed vegetable soup.
Let us assume the total number of tomatoes and carrots be x. So, as per the mentioned information, the equation will be -
40%×x = 50
Converting percentage to fraction
40/100×x = 50
x = 50×100/40
Cancelling zero and performing division
x = 5×25
Performing multiplication
x = 125
Total number of vegetables = number of tomatoes + number of carrots
125 = 50 + Number of carrots
Number of carrots = 125 - 50
Performing subtraction
Number of carrots = 75
Therefore, Jan should use 75 carrots.

Using simple interest, the amounts she invested are given as follows:
$3,000 at 9%.$1,500 at 6%.Simple InterestSimple interest is used when there is a single compounding per time period, usually measured in years.
The amount of money after t periods in is modeled by:
A(t) = P(1 + rt)
The interest accrued after t periods is modeled by:
I(t) = Prt
In which:
P is the initial amount.r is the interest rate, as a decimal.She had two investments, investing a total of $4500, hence:
[tex]P_1 + P_2 = 4500[/tex]
The return for the 9% investment exceeds that from the 6% investment by $180, hence:
[tex]I_2 = 0.06(4500 - P_1)[/tex][tex]I_1 = 0.09P_1[/tex][tex]I_2 = I_1 - 180[/tex]Then:
