How do you solve linear inequality step by step?
Solving a linear inequality step by step involves several steps including isolating the variable on one side of the inequality sign, simplifying the inequality, graphing the inequality, shading the region that include the solutions and representing the solutions in the form of an interval.
1. Isolate the variable on one side of the inequality sign: This can be done by adding or subtracting the same value from both sides of the inequality, or by multiplying or dividing both sides by the same non-zero value.
2. Simplify the inequality: This can include combining like terms, or simplifying fractions or decimals.
3. Graph the inequality: This can be done by plotting the inequality on a number line or a coordinate plane, using a solid line for "greater than" or "less than" and a dotted line for "greater than or equal to" or "less than or equal to"
4. Test a point: To test whether a point is a solution of the inequality, substitute the coordinates of the point into the inequality, and check if the statement is true.
5. Shade the region that includes the solutions: The solutions of the inequality are all the points that make the inequality statement true. The solutions of the inequality are all the points that are in the shaded region.
6. Write the solution in interval notation: Write the solution in interval notation, if needed.
Here is an example:
Solve the inequality 2x - 3 > 5.
Step 1: Isolate the variable by adding 3 to both sides: 2x > 8
Step 2: Divide both sides by 2: x > 4
Step 3: Graph the inequality on a number line. Using a solid line, draw a line at x = 4 and shade the region to the right of the line, including 4.
Step 4: Test a point, e.g. x = 5, if 5 > 4 is true.
Step 5: The solution is x > 4.
Step 6: if needed, the solution can be written in interval notation as (4, +inf)
It's important to note that solving inequalities is not always straightforward, and some inequalities may require multiple steps to be solved.

Is it possible to construct a triangle whose sides are 3.5 cm 9.2 cm and 5.3 cm Why or why not?
The triangle can be constructed from sides of triangle measuring 3.5 cm 9.2 cm and 5.3 cm due to side rule of triangle.
The possibility to construct the triangle will be found out through the sum of any two sides of triangle. If the sum is greater than the remaining side of the triangle, the construction is possible. Let us assume the side a, b and c of triangle to be 3.5, 9.2 and 5.3 cm.
Now, using the side-side-side rule of triangle -
Side a + side b > side c
3.5 + 9.2 > 5.3
Add the values
12.7 > 5.3
Side b + side c > side a
9.2 + 5.3 > 3.5
Add the values
14.5 > 3.5
side c + side a > side b
5.3 + 3.5 > 9.2
Add the values
8.8 not greater than 9.2

The lengths of two sides of a triangle are 5 and 14. Find the lengths that the third side must be greater than and less than.
Answer:
The third side of the triangle must be greater than 4 and less than 19. This follows from the Triangle Inequality Theorem, which states that the sum of any two sides of a triangle must be greater than the third side, and the difference between any two sides of a triangle must be less than the third side. Therefore, the third side must be greater than 4 (5 + 4) and less than 19 (14 - 4).

What should be added to 2x2 xy 2y2 to obtain 3x2 5xy?
To obtain 3x² + 5xy from 2x² + 2xy², you would need to add the polynomial x² + 5xy to the original expression.
In order to add two polynomials together, the terms must have the same degree and variable. In this case, we see that 2x^2 and 2xy^2 have different degrees and variables. So, we need to find a polynomial that when added to 2x² + 2xy² will give us 3x² + 5xy.
To do this, we can start by looking at the x² term in 3x² + 5xy. We can see that we need to add x² to our original polynomial. Next, we can look at the xy term in 3x² + 5xy. We can see that we need to add 5xy to our original polynomial.
So by adding x² + 5xy to 2x² + 2xy², we get the desired polynomial of 3x² + 5xy.

Is 4 6 and 2 3 equivalent?
So we can write 4/6 as equivalent to 2/3
What is Equivalent ?Equal is not the same as equivalent. While comparable indicates similar but not the same, equal means the same in all respects. For instance, 1 + 1 is comparable to 2, even if 2 is supposed to be equal to 2.
Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value for the variable, two algebraic expressions that are equivalent have the same value.
The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since 2/4 and 3/6 both equal the 1/2, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.

How do you find the center and radius of an endpoint?
To find the center and radius of a circle given the endpoints of its diameter, you can use the following steps:
Find the midpoint of the diameter: The midpoint of the diameter is the center of the circle. To find the midpoint, you can use the midpoint formula: (x,y) = ((x1 + x2)/2, (y1 + y2)/2), where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the diameter.Find the radius: The radius of a circle is half the length of its diameter. To find the radius, you can use the distance formula to find the distance between the two endpoints of the diameter: d = √((x2 - x1)^2 + (y2 - y1)^2) and divide the result by 2.For example, if the endpoints of a diameter are (-3, 4) and (7, -6), you can use the midpoint formula to find the center:
(x,y) = ((-3 + 7)/2 , (4 + -6)/2)
(x,y) = (2,-1)
The center of the circle is (2,-1)
To find the radius, you can use the distance formula:
d = √((7-(-3))^2 + (-6-4)^2)
d = √((10)^2 + (-10)^2)
d = √(100+100)
d = √200
d = 10√2

How do you find the side lengths of a 45 45 90 triangle?
The side lengths of a 45-45-90 triangle can be found using side ratios or the formula that the length of hypotenuse is root two times the length of each leg which is equal.
A 45-45-90 triangle is a special type of right triangle that has two angles that measure 45 degrees and one angle that measures 90 degrees. This triangle has a unique relationship between its side lengths.
The length of the hypotenuse (the side opposite the 90-degree angle) is equal to √2 times the length of one of the legs (the two sides that are congruent and form the 45-degree angles).
The length of each leg is equal to the length of the hypotenuse divided by √2.
For example, if the hypotenuse of a 45-45-90 triangle measures 8 units, then one leg measures 8/√2 = 8/1.4142 = 5.6568 units, and the other leg measures also 8/√2 = 8/1.4142 = 5.6568 units.
Another way to find the side lengths of a 45-45-90 triangle is to use the side ratios. The ratio of the sides in a 45-45-90 triangle is 1:1:√2, so if you know the length of one side, you can find the length of the other sides using these ratios.
It's important to keep in mind that a 45-45-90 triangle is a special type of triangle and its side lengths can be found using the formulas and ratios mentioned above. Regular triangles, such as a 30-60-90 triangle, have also similar relationships between their sides.
