By completing squares, we can rewrite the quadratic equation as:
(x + 9)^2 = -9
How to complete squares?Remember the perfect square trinomial:
(a + b)^2 = a^2 + 2ab + b^2
Here we have the quadratic equation:
x^2 + 103 = -18x + 13
We can rewrite this as:
x^2 + 18x = 13 - 103
x^2 + 18x = -90
x^2 + 2*9*x = -90
We can add 9^2 and subtract 9^2 to get:
x^2 + 2*9*x + 9^2 - 9^2= -90
(x^2 + 2*9*x + 9^2) - 9^2= -90
(x + 9)^2 - 81 = -90
(x + 9)^2 = -90 + 81
(x + 9)^2 = -9
That is the equation we wanted to get.

Sundeep mixed 300 mL of water with 100 mL of sugar. She says "the total volume is
300 mL + 100 mL = 400 mL." Do you agree with Sundeep? Explain why or why not.
No, I don't agree with Sundeep. The mixture wont simply add up
How to show the volume will not be 400 mlWhen two liquids are mixed together, their volumes don't simply add up to equal the total volume of the mixture.
When sugar is mixed with water, the total volume of the mixture is usually slightly greater than the volume of the water alone, because the sugar particles take up space between the water molecules.
The volume of the mixture will be equal to the sum of the individual volumes only if the two liquids are completely immiscible, meaning they don't mix together at all. In this case, the total volume of the mixture will be equal to the sum of the volumes of water and sugar, which is 400 mL.

Is (-5, -5) a solution to this system of equations?
=
y = -x - 7
y = x-3
yes
no
Answer:
no
Step-by-step explanation:
equate the two equations (make them equal to each other)
-2/5x - 7 = 2/5x - 3
get rid of the fractions by multiplying everything by 5
5(-2/5x - 7 = 2/5x - 3)
-2x - 35 = 2x - 15
solve
-2x - 35 = 2x - 15
-2x - 2x = -15 + 35
-4x = 20
x = -5
plug in "x" to one of the starting equations (I'm using the second one)
y = 2(-5) - 15
y = -10 - 15
y = -25
an easier way would be to plug in the point for "x" and "y"
-5 = 2(-5) - 15
-5 = -10 - 15
-5 = -25 FALSE
La sexta parte de la diferencia de dos números. En oración algebraica
The phrase "La sexta parte de la diferencia de dos números" in algebraic sentence can be written as \( \frac{x}{6} \) where "x" represents the difference between two numbers.
The quantity \( \frac{x}{6} \) is a fraction that represents one-sixth of the difference between two numbers. In other words, if you have two numbers "a" and "b", and you subtract them to find their difference "a-b", then \( \frac{x}{6} \) would equal \( \frac{(a - b)}{6} \).
The fraction \( \frac{x}{6} \) gives us a portion or a ratio of the difference between the two numbers, and in this case, it's one-sixth of that difference. So, if you want to find what one-sixth of the difference between two numbers is, you can simply divide that difference by 6.
Let's say that the two numbers you want to find the difference between are 15 and 6. To find their difference, we would subtract the smaller number from the larger one:
15 - 6 = 9
So, the difference between these two numbers is 9. To find one-sixth of this difference, we would divide the difference by 6:
\( \frac{9}{6} = 1.5\)
So, one-sixth of the difference between 15 and 6 is 1.5.

Notice that the side PL in one triangle has the same length as side GJ in the other, and side GH has the same size as side LK of the other triangle. Now what is different is the angle subtended between these sides in the case of the triangle on the lower left, the subtended angle is \(90^o\) , which is larger angle than that subtended between equal sides on the other triangle (\(85^o\))
Therefore, if the angle subtended by the equivalent sides in the triangle on the left is larger than the angle subtended on the right hand side triangle, then the sides associated with such angle aperture must keep the inequality. That is:
Since \(\angle\,G\,\,\,>\,\,\,\angle \,L\), then HJ > PK
A composite figure is made up of two rectangles and a right triangle. The figure and its dimensions in centimeters are shown in the diagram. What is the area of the composite figure in square centimeters?
The area of the composite figure is 336 centimeters²
Since, A right triangle or right angled triangle, or more formally an orthogonal triangle, formerly referred as rectangle triangle, is a triangle in which one angle is a right angle, that is in which two sides are perpendicular to each other. It forms the basis of trigonometry on the basis of its sides and angles.
Now, The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units like cm2 and m2. Area of a shape is a two dimensional quantity.
Divide the composite figure into smaller shapes.
A is a rectangle with width 6cm and length 12cm
Hence, Area of A= 12 x 6 = 72cm²
B is a triangle with base 6cm and height 8cm
Therefore area of triangle=1/2 x base x height
= 1/2 x 6x 8 = 24cm²
C is a rectangle with breadth 30cm and length 8cm

4x(x + 1) − (3x − 8)(x + 4)
The simplified form of the expression 4x(x + 1) − (3x − 8)(x + 4) is -3x^2 - 4x - 32.
To simplify the expression 4x(x + 1) − (3x − 8)(x + 4), we can expand the parentheses and combine like terms.
Expanding the first term, we get 4x^2 + 4x.
Expanding the second term, we have -(3x)(x) - (3x)(4) - (-8)(x) - (-8)(4), which simplifies to -3x^2 - 12x - (-8x) - (-32), further simplifying to -3x^2 - 12x + 8x - 32.

The total income and expenditure of Agri-small business limited in September is R 299596 and expenditure is R 193236.
How to find the Expense?We have to find the total income and expenditure in September.
The equation for insurance is mathematically given as :
Insurance = 42% of the balance
Insurance=0.42*0.64A
Insurance=0.2688A.
Total expenditure after all other expenditures = 0.64A-0.2688A
Total expenditures after all other expenditures = 0.3712A.
Total expenditures after all other expenditures is as 111210 (106360 +4850)
Equating both the equation and value:
111210 = 3712 A
A = 299596
Thus The total income is 299596.
Therefore the calculation of expense is given as:
Expense=0.25A+0.11A+0.2688A+4850
Expense=0.6288A+4850
=0.6288*299596+4850

Determine the turning points and distinguish between them when necessary y=x³ - 3x - 9x + 4
The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).
To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.
1. Find the derivative of the function:
y' = 3x² - 6x - 9
2. Set the derivative equal to zero and solve for x:
3x² - 6x - 9 = 0
3. Factorize the quadratic equation:
3(x² - 2x - 3) = 0
4. Solve the quadratic equation by factoring or using the quadratic formula:
(x - 3)(x + 1) = 0
This gives us two possible values for x: x = 3 and x = -1.
5. Substitute these critical points back into the original function to find the corresponding y-values:
For x = 3:
y = (3)³ - 3(3)² - 9(3) + 4
= 27 - 27 - 27 + 4
= -23
For x = -1:
y = (-1)³ - 3(-1)² - 9(-1) + 4
= -1 - 3 + 9 + 4
= 9
6. Therefore, the turning points are (3, -23) and (-1, 9).
Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

The 95% confidence interval of the mean body temperature of adults in the town is (97.584, 98.876)°F (open-interval notation), accurate to 3 decimal places.
What is the 95% confidence interval of the mean body temperature of adults in the town?To find the 95% confidence interval (C.I.) of the mean body temperature, we need to use the formula:
C.I. = x ± z*(σ/√n)
Where:
x is the sample mean
σ is the population standard deviation (unknown, but we can estimate it using the sample standard deviation)
n is the sample size
z is the critical value for the desired confidence level (95% in this case)
First, we need to calculate the sample mean, sample standard deviation, and sample size:
x = (98 + 97.9 + 99 + 97.3 + 98.9 + 99.6 + 97.8 + 99.8 + 99.1 + 98.4 + 98.7 + 97.6 + 96.5) / 13 = 98.23
s = √((1/(n-1)) * Σ(xi - x)²)
s = 1.339
n = 13
Next, we need to find the critical value, z, for a 95% confidence level. We can look this up in a standard normal distribution table or use a calculator. For a 95% confidence level, z = 1.96.
Now we can plug in the values into the formula to get the 95% confidence interval:
C.I. = 98.23 ± 1.96*(1.339/√13) = (97.584, 98.876)

Given f(x) = 2x2 − 3x + 7, find f(2.5)
Answer:
12
Step-by-step explanation:
Given that,
f(x) = 2x² - 3x + 7
To find the value of f ( 2.5 ), replace x with 2.5 and solve the equation.
Let us solve it now.
f(2.5) = 2(2.5)² - 3×2.5 + 7
f(2.5) = 12.5 - 7.5 + 7
f(2.5) = 12
Answer:
\(f(x) = 2 {x}^{2} - 3x + 7 \\ f(2.5) = 2 {(2.5)}^{2} - 3(2.5) + 7 \\ f(2.5) = 12.5 - 7.5 + 7 \\ \boxed{f(2.5) = 12}\)
f(2.5) = 12 is the right answer.If Fran were to paint her living room alone, it would take 6 hours. Her sister Denise could do the job in 8 hours. How many hours would it take them working together? Express your answer as a fraction reduced to lowest terms, if needed.
It would take Fran and Denise (working together) approximately \(\frac{24}{7}\) hours to paint the living room.
To solve this problem, we can use the concept of "work rates."
Let's find out how much work Fran and Denise can do individually in one hour.
If Fran takes 6 hours to paint the living room alone, her work rate is \(\frac{1}{6}\) of the room per hour \((\frac{1 room}{6 hours } = \frac{1}{6}room/hour )\).
Similarly, if Denise takes 8 hours to paint the living room alone, her work rate is \(\frac{1}{8}\) of the room per hour \((\frac{1 room}{8 hours } =\frac{1}{8}room/hour )\).
When they work together, their work rates are additive.
So, their combined work rate would be:
\(\frac{1}{6} room/hour+\frac{1}{8} room/hour\)
\(=(\frac{4}{24} )room/hour + (\frac{3}{24} )room/hour\)
\(=\frac{7}{24} room/hour\)
This means that working together, Fran and Denise can paint \(\frac{7}{24}\) of the living room in one hour.
To determine the total time required for them to paint the entire room, we can invert their combined work rate:
\(\frac{(1 room) }{(\frac{7}{24}room/hour) } =\frac{24}{7}hour\)
Therefore, it would take Fran and Denise (working together) approximately \(\frac{24}{7}\) hours to paint the living room.
