The first step in solving an inequality is to isolate the variable on one side of the inequality sign. This is also known as "clearing the inequality" of the variable. This can be done by using inverse operations such as addition, subtraction, multiplication, and division.
For example, if the inequality is 3x + 2 > 7, the first step is to isolate the variable x by subtracting 2 from both sides:
3x + 2 > 7
3x > 5
Then, divide both sides by 3 to get x > 5/3
This is the first step in solving an inequality, as now the variable x is isolated on one side of the inequality sign, and it's clear what the inequality is asking for.
It's important to note that when solving inequalities, it's crucial to keep the direction of the inequality sign the same, meaning if you multiply or divide by a negative number, you need to switch the direction of the inequality sign as well.
Also, it's important to check if the inequality is not valid, if the operation you are doing creates a division by zero, it will be an invalid inequality.

if In = 5 x" (1+x)0.5 dx ,n= 0,1,2....
where the integral is for x e [0,1].
By first finding a bound on the integrand, which of these is an upper bound on In?
Pick ONE option
O 1/(n+1)
O 1/2(n+1)
O 1/(n+1) + 1/(n+2)
O N^N
The correct option is 1/(n+1).The upper bound for the integral is 1/(n+1).
To determine the upper bound, we can use the fact that the integrand is bounded by its maximum value on the interval. The maximum value of the integrand on the interval [0, 1] is:
f(x) = 5x(1 + x)^(0.5)
At x = 1, f(x) = 5(1 + 1)^(0.5) = 5√2.
Therefore, an upper bound for the integral is:
In ≤ 5√2∫x^n dx
0
Using integration by parts, we obtain:
In ≤ 5√2[x^(n + 1)/(n + 1)]_0^1
= 5√2/ (n + 1)
Therefore, the upper bound for the integral is 1/(n+1).

Write an equation of the perpendicular bisected of the segment with endpoints (3,7) and (-1,-5)
The equation of perpendicular line that bisects the line segment is y = - (1 / 3) · x + 4 / 3.
How to find the equation of the perpendicular line that bisects a line segment
In this problem we must determine the equation of the line that is perpendicular to a line segment and partitions the line segment in two parts of equal length, it happens when the perpendicular line passes through the midpoint of the line segment.
The equation of the line in explicit form is shown below:
y = m · x + b
Where:
m - Slopeb - Interceptx - Independent variabley - Dependent variableIn addition, two lines are perpendicular to each other when the following relationship is observed:
m · m' = - 1
Where:
m - Slope of the original line.m' - Slope of the perpendicular line.Besides, the slope of a line can be determined by secant line formula:
m = Δy / Δx
Where:
Δx - Change in independent variable.Δy - Change in dependent variable.And lastly, the midpoint of a line segment is determined by this formula:
M(x, y) = 0.5 · A(x, y) + 0.5 · B(x, y)
First, find the midpoint of the line segment:
M(x, y) = 0.5 · (3, 7) + 0.5 · (- 1, - 5)
M(x, y) = (1.5, 3.5) + (- 0.5, - 2.5)
M(x, y) = (1, 1)
Second, determine the slope of the line related to line segment:
m = (- 5 - 7) / (- 1 - 3)
m = (- 12) / (- 4)
m = 3
Third, calculate the slope of the perpendicular line:
3 · m' = - 1
m' = - 1 / 3
Fourth, find the intercept of the equation of perpendicular line:
b = y - m · x
b = 1 - (- 1 / 3) · 1
b = 1 + 1 / 3
b = 4 / 3
Fifth, write the equation of perpendicular line:

How do the functions from part a differ from functions you have used in algebra in the past?
The functions differ from functions that we have used in algebra in the past as the functions can be combined and are more about rotation rather than where they move.
An output variable and one or more input variables are the minimum number of variables in a function.
An equation can have any number of variables and declares that two expressions are equal (none, one, or more). Although not all equations are functions, a function is frequently expressed as an equation.
It should be recalled that a function is merely an equation in which the x inserted produces precisely one from the equation.
In this instance, the functions are different from the ones we have used in algebra in the past since they may be coupled and focus more on rotation than on where they travel.

The corollary interior angles theorem is a mathematical result that relates to the number of sides in a polygon and the sum of the interior angles of that polygon.
What is corollary interior angles theorem?The corollary interior angles theorem states that if a polygon has n sides, then the sum of its interior angles is equal to (n-2) times 180 degrees. This theorem is a direct result of the interior angle theorem, which states that the sum of the interior angles of a polygon with n sides is equal to (n-2) times 180 degrees. To prove the corollary interior angles theorem, we first consider a triangle with three sides. The sum of the interior angles of a triangle is equal to 180 degrees, which confirms that the interior angle theorem holds for a triangle. We can then use this result to extend the theorem to polygons with more sides by induction. If we add one more side to the polygon, the sum of the interior angles increases by 180 degrees. By continuing this process and adding sides to the polygon, we can conclude that the sum of the interior angles of a polygon with n sides is equal to (n-2) times 180 degrees. This confirms the corollary interior angles theorem.

Find the range for the measure of the third side of a triangle when the measures of the other two sides are 18 ft and 23 ft.
Answer:
The measure of the third side of a triangle, when the measures of the other two sides are 18 ft and 23 ft, must be greater than the difference between the measures of the other two sides (which is 18 ft - 23 ft = -5 ft) and less than the sum of the measures of the other two sides (which is 18 ft + 23 ft = 41 ft).
This is because according to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. So the measure of the third side must be between the difference of the two given sides and the sum of the two given sides.
Therefore the range of the measure of the third side of a triangle with side lengths 18 ft and 23 ft is:
(-5 ft < x < 41 ft)
or
[x > -5 ft and x < 41 ft].
It is also important to note that any value of x within this range will produce a valid triangle, however, any value less than -5 or greater than 41 will not.
