Answer:9 less than 9 is 0
Step-by-step explanation:
9-9=0
Answer:
9
Step-by-step explanation:
Less means minus, so basically X ( something ) - 9 is 0
X - 9 = 0
You add 9 on each side
X = 0 + 9
X = 9
Basically, all you're doing is the reverse, you start with 0 and do the opposite of taking away 9 which is adding nine so that you get the number:
0 + 9 = 9
Hence the number is 9

What is power?
Power is the ability to influence or control the behaviour of others, and to make decisions that affect the outcome of any given situation. It is a form of force that can be both positive and negative, and can be used in various ways. Power can come from a variety of sources, such as money, status, knowledge, physical strength, and social standing. It is a form of authority that can be used to motivate and inspire others, or to manipulate and coerce them. Power is an important part of many social and political systems, and is essential for effective leadership. It is an essential tool for achieving desired outcomes and can be used for good or for ill. Ultimately, power is a form of influence, and its use depends on the individual wielding it.
In general, if a is a positive real number and n is a positive integer, then a^(n/2) is equal to the square root of a^n. This can be written as:
a^(n/2) = sqrt(a^n) = a^(1/2) * a^(1/2)

The value of h(-5) in the given function, h(x) = -3|x - 1| + 4, is h(-5) = -14
Evaluating a functionFrom the question, we are to evaluate the given function for the given value
The given function is
h(x) = -3|x - 1| + 4
We are to determine the value of h(-5).
To determine the value of h(-5), we will substitute -5 for x in the given function.
That is,
h(x) = -3|x - 1| + 4
h(-5) = -3|(-5) - 1| + 4
h(-5) = -3|-5 - 1| + 4
h(-5) = -3|-6| + 4
h(-5) = -3(6) + 4
h(-5) = -18 + 4
h(-5) = -14

Jack and andrea want to create a right triangle together using values of x and y and the polynomial identity to generate pythagorean triples. If andrea picks a value of x = 2, and the hypotenuse of the resulting right triangle is 5, what natural number value of y did jack pick?.
On solving the provided question, we got that - y = 4, when x=2 and the hypotenuse of the resulting right triangle is 5.
What is the formula for the Pythagorean theorem?[tex]AC^2 = AB^2 + BC^2[/tex] is the formula for the Pythagorean theorem, where AB is the perpendicular, BC is the base, and AC is the hypotenuse. All triangles with 90° angles are governed by the Pythagorean equation.
The hypotenuse formula can be used to define the relationship between the sides of a right triangle, making it a specific kind -
[tex]c^2 = a^2 + b^2\\or\\c^2 = x^2 + y^2[/tex]
where,
The triangle's hypotenuse, or c, is the side that faces away from the 90-degree angle.
while the sides closest to the 90° angle are denoted by a and b.
Given that the hypotenuse is 5 = c and one of the sides has a measure of 2 = x in the issue statement, we can calculate for y as follows:
[tex]y^2 = c^2 - x^2\\y^2 = 5^2 - 2^2\\y^2 = 21\\y = 4.58[/tex]
The number before the decimal is known as the natural number. As a result, the response is:

Augustus Galoop (from Willie Wonka & The Chocolate Factory) LOVED
chocolate. He loved it SO MUCH, he decided to create his very own chocolate
milk He made 30 gallons (he REALLY loves chocolatel). The mixture had to be
perfect, so he started with a recipe of 10% chocolate syrup and 90% milk It
was too weak, so he tried 30% chocolate & 70% milk That was even too
chocolaty for him. "Maybe, If I try 15% chocolate syrup & 85% milk, it'll be
perfect??" So he did, but he forgot how many gallons of chocolate syrup & milk he'd
used for the first two attempts. He DID remember the percentages, though. How
many gallons of chocolate syrup & milk did he use for his final mixture?
Augustus used a total of 12 gallons + 1.8 gallons = 12+1.8=13.8 gallons of chocolate syrup in the three mixtures.
What is a percentage?
Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) besides the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
Since Augustus used 10% chocolate syrup and 90% milk for the first mixture and 30% chocolate syrup and 70% milk for the second mixture, the total percentage of chocolate syrup he used in the first two mixtures is 10% + 30% = 40%.
Since Augustus made a total of 30 gallons of chocolate milk, he used 30 gallons * 40% =3040.01=12 gallons of chocolate syrup in the first two mixtures.
For the final mixture, Augustus used 15% chocolate syrup and 85% milk. The total percentage of chocolate syrup he used for the final mixture is 15%.
Since Augustus used a total of 12 gallons of chocolate syrup in the first two mixtures, he used an additional 12 gallons * 15% = 1215.01=11.8 gallons of chocolate syrup for the final mixture.
Hence, Augustus used a total of 12 gallons + 1.8 gallons = 12+1.8=13.8 gallons of chocolate syrup in the three mixtures.

b. Prove the equivalence of the two expressions using algebraic manipulation.
Answer:
The two expressions are equivalent, based on a direct numerical comparison (a) and (b) a methematical comparison.
Step-by-step explanation:
a) The expressions can be shown to be equivalent by entering the numbers into each expression and comparing the results. This is easy with a spreadsheet program. Set up a table with the values of x in the left column. Then enter the 2 equations in the first entry (-2) in each of two subsequent columns. These expressions can be copied to the other rows by clicking on the first cell and dragging the lower right corner down until all rows are included. The copied expressions will select the corresponding value of x for both expressions, as shown in the attached table. It can be seen that both expressions yield the same results.
b) Prove the equivalence mathematically:
In other words, do the two expressions equal each other?
(12x^2 - 27)/3 = -(-2x+3)(2x+3) ??
Simplify both sides
(4x^2 - 9) = -(-4x^2 + 9) ?

Step-by-step explanation:
Given m||n, find the value of x ( x+1) (7x-5)
Answer: If two lines are parallel, it means that they have the same slope. Therefore, to find the value of x in this problem, you need to find the slope of line m and line n, and then set them equal to each other.
The slope of a line can be found using the formula:
slope = (y2 - y1)/(x2 - x1)
In this case, you are given the equation of line m in the form "x + 1", and the equation of line n in the form "7x - 5". To find the slope of each line, you can rewrite these equations in the form y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).
For line m, we have:
y = x + 1
The slope of this line is m = 1.
For line n, we have:
y = 7x - 5
The slope of this line is m = 7.
Since line m and line n are parallel, their slopes must be equal. Therefore, we can set these slopes equal to each other and solve for x:
1 = 7
This equation has no solution, which means that there is no value of x that will make these two lines parallel. Therefore, the answer is that there is no solution.
