The range of temperatures on a particular day could be described as |x-68|<=9. How many integer values are included in this range?
(1) There are 2b+1 integer solutions to the equation x-a=b. (2) and (2) There are 2b-1 integer solutions to the equation x-a = b.
what is integers ?Integers include 0 as well as positive and negative numbers that are indicated by minus signs. An equivalent positive number's additive reciprocal is a negative number. In mathematical notation, a group of integers is typically denoted by a bold Z or a bold "mathbb Z." An integer is a number that can be positive, negative, or zero and is not a fraction (pronounced IN-tuh-jer). An example of an integer is the number -5, 1, 5, 8, 97, and 3,043 Non-integer examples are 1.43, 1. 3/4, 3.14, and other numbers. A group of integers and their antipodes are known as integers. The set of integers excludes decimals and fractions.
given
This type of absolute value difficulty can be resolved by interpreting the expression x-a = b as indicating that the difference between x and an is at most b. Therefore, x is only 9 away from 68 if x-68 = 9. 68-9 = 59; 68+9 = 77. (77-59)+1 = 19 is the total number of integers from 59 to 77, inclusive.
A) Using the same meaning, x must be closer to -4 by no more than 8 than usual. -4-8 = -12; -4+8 = 4. The integer solutions range from -11 to 3 inclusive, or 15 numbers, because this is a rigorous inequality.
B) This one indicates that x is only three values away from five, ranging from three to seven.
(1) There are 2b+1 integer solutions to the equation x-a=b. (2) and (2) There are 2b-1 integer solutions to the equation x-a = b.

Given the sequence 2 and one half comma 2 and one third comma 2 and one fourth comma and continues comma what is f (n)?.
From the sequence 2 [tex]\frac{1}{2}[/tex], 2 [tex]\frac{1}{3}[/tex], 2 [tex]\frac{1}{4}[/tex], ..., f(n) can be expressed as 2 + [tex]\frac{1}{(n+1)}[/tex] where n is the term number in the sequence. Hence, the correct answer is A.
Each term in the sequence is 2 plus a fraction where the denominator is one more than the term number. For example:
In the first term, n=1 and the fraction is [tex]\frac{1}{2}[/tex] In the second term, n=2 and the fraction is [tex]\frac{1}{3}[/tex]In general, the n-th term in the sequence will have the fraction [tex]\frac{1}{(n+1)}[/tex].
Therefore, the function f(n) that generates this sequence is 2 + [tex]\frac{1}{(n+1)}[/tex]. This function takes an input of n and outputs the corresponding term in the sequence.
This question should be written as:

What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

What quadrant is ordered pair 4 3?
An ordered pair (x,y) represents a point on a coordinate plane, where x is the horizontal position and y is the vertical position. The quadrant in which this point lies can be determined by the signs of the x and y coordinates.
The quadrant that contains the point (4,3) is Quadrant 1. This is because both the x-coordinate (4) and y-coordinate (3) are positive, indicating that the point lies in the top-right region of the coordinate plane.
Why is the formula for the area of a triangle 1 2BH?
The formula for the area of a triangle is 1/2bh. This formula can be derived from the area of a parallelogram.
A parallelogram is a four-sided shape with two pairs of parallel sides. To find the area of a parallelogram, you need to multiply the base, b, by the height, h. This will give you the area of the parallelogram, which is bh. To find the area of a triangle, you need to divide the area of a parallelogram by two since a triangle has only one set of parallel sides. Therefore, the formula for the area of a triangle is 1/2bh. To calculate the area of a triangle, you need to multiply the base by the height and then divide the result by two. For example, if the base of a triangle is 8 cm and the height is 4 cm, the area of the triangle is 1/2 × 8 × 4 = 16 cm2.

How do you prove the change of base formula?
The change of base formula states that for any logarithm base b and any positive number x: log_b(x) = (log_c(x)) / (log_c(b)), where c is any base.
The change of base formula is a mathematical formula that allows you to convert a logarithm with one base to a logarithm with another base. The formula states that for any logarithm base b and any positive number x: log_b(x) = (log_c(x)) / (log_c(b)), where c is any base.
One way to prove this is to use the properties of logarithms:
log_b(x × y) = log_b(x) + log_b(y)log_b(xⁿ) = n × log_b(x)Using these properties, we can write log_b(x) as:
log_b(x) = log_b([tex]c^{(log_c(x))}[/tex])
log_b(x) = log_b([tex]c^{(log_c(x))}[/tex]) / log_b(c¹)
log_b(x) = log_c(x) / log_c(b)
Therefore, the change of base formula is proven.

In mathematics, an inequality makes a link among two values that do not equal. Egality and inequality are different. The not equal symbol is typically used to indicate that two values are also not equal (). Different inequalities are employed to contrast values of all sizes. By changing the two parts until only the variables are left, one can solve many straightforward inequalities. Negative values are split or added on either side. Switch between the left and right.

Can you construct a triangle with sides 17 cm 7 cm 8 cm?
Answer:
In order to form a triangle, the sum of the length of two sides should be greater than the length of the third side. This is called the triangle inequality theorem.
Given the side lengths of 17 cm, 7 cm, and 8 cm, we can see that 17 cm is the longest side. To form a triangle, the sum of the other two sides (7 cm and 8 cm) should be greater than 17 cm.
7 cm + 8 cm = 15 cm which is less than 17 cm. Therefore, it is not possible to construct a triangle with sides 17 cm, 7 cm, and 8 cm.

Express the absolute value function f(x)=9|x| as a piecewise-defined function.
Answer:
[tex]f\left(x\right)=\begin{cases}-9x&x\: < \:0\\ \:\:\:9x&x > \:0\end{cases}[/tex]
Step-by-step explanation:
The first thing to note is that absolute value functions are piecewise functions.
A piecewise function is a function in which more than one formula is used to define the output over different pieces of the domain or inputs(in this case the x-values).
In this case, the absolute value function is
[tex]f(x) = 9|x|[/tex]
To write this function as a piecewise function you have to use the definition of [tex]f(x) = |x|[/tex] :
[tex]f\left(x\right)=\begin{cases}-x&x\: < \:0\\ \:\:\:x&x > \:0\end{cases}[/tex]
Applying this to [tex]9|x|[/tex] we multiply each of the parts by 9 to get
[tex]f\left(x\right)=\begin{cases}-9x&x\: < \:0\\ \:\:\:9x&x > \:0\end{cases}[/tex]
At [tex]|x| = 0, f(x) = 9|x| = 0\\[/tex]

In general, if the directrix is parallel to the y-axis in the standard equation of a parabola is given as:
y^2 = 4ax
If the parabola is sideways i.e., the directrix is parallel to x-axis, the standard equation of a parabola becomes,
