The types of solutions for an equation depend on the type of equation, but in general, the most common types of solutions are: single solution, no solution and infinite solutions.

In mathematics, particularly in algebra, a solution of an equation is a value or a set of values that, when substituted into the equation, makes it a true statement.

Single solution: An equation has a single solution when it has exactly one value that satisfies the equation. This solution is unique and it can be found by solving the equation for the variable.

No solution: An equation has no solution when it is impossible to find a value that satisfies the equation. This happens when the equation is contradictory or inconsistent. For example, the equation "2x = 5x + 1" has no solution because no value of x can make the equation true.

Infinite solutions: An equation has infinite solutions when any value of the variable satisfies the equation. This happens when the equation is an identity, meaning it is true for all values of the variable. For example, the equation "2x + 0 = 2x" has infinite solutions because any value of x will make the equation true.

Factor the radicand: If the radicand is not already in the form of a perfect square, you can factor it into its prime factors and pull out any perfect squares from the radicand.

For example, √(36) can be simplified to √(49) = √4 * √9 = 23.

Simplify the exponent: If the radical has an exponent (such as cube root), divide the exponent by the index of the radical. Example ∛64 = ∛(4^3) = ∛4 * ∛4 * ∛4 = 4 *4 *4 =4

Combine like factors: If there are any factors in the radicand that match the exponent, you can combine them and simplify the radical further. For example, √(2235) = √(2^235) = 2√(35) = 2√15 = 2*3 = 6.

It is important to note that not all radicals can be simplified to a whole number or a fraction. In some cases, the radical will be in its simplest form when it is left as an irrational number.

For Example, √2 cannot be simplified further.

(5a - 6)(5a + 6)

The correct answer is D

The inequality form of the statement is: |4x - 2| ≤ 2. And the lowest value of x that makes this inequality true is x = -1.

To solve for the lowest value of x that makes this inequality true, we need to consider two cases:

If 4x - 2 ≥ 0, then |4x - 2| = 4x - 2, so the equation becomes:

4x - 2 ≤ 2

Adding 2 to both sides, we get:

4x ≤ 4

Dividing both sides by 4, we get:

x ≤ 1

If 4x - 2 < 0, then |4x - 2| = -(4x - 2), so the equation becomes:

-(4x - 2) ≤ 2

Adding 2 to both sides, we get:

-4x + 4 ≤ 4

Dividing both sides by -4, we get:

x ≥ -1

So, the solution to the inequality is -1 ≤ x ≤ 1. This means that any value of x that lies between -1 and 1, inclusive, satisfies the inequality.

So, the lowest value of x that makes this inequality true is x = -1.

The polynomial function is obtained to be h(x) = -2 (x - 4)(x - 1)²(x + 2), with the values a = -2, b = -4, c = -1 and d = 2.

What is a polynomial?

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

The characteristics of the polynomial are -

The zeros are located at 4, 1 (multiplicity of 2) and-2

The end behavior is as follows -

As x reaches negative infinity, f(x) reaches negative infinity.

As x reaches infinity, f(x) reaches negative infinity.

The y-intercept of the function is (0, 16)

The equation of h(x) can be written as -

h(x) = a(x+b)(x+c)²(x+d)

The zeroes of the polynomial can be written as -

x = 4 ⇒ (x - 4)

x = 1 ⇒ (x - 1)

x = 1 ⇒ (x - 1)....Since the multiplicity is 2 so write it two times.

x = -2 ⇒ (x + 2)

So, the equation will be -

y = a (x - 4)(x - 1)(x - 1)(x + 2)

The y-intercept is given as (0,16).

So, substitute the values of x and y with 0 and 16 respectively.

y = a (x - 4)(x - 1)(x - 1)(x + 2)

16 = a (0 - 4)(0 - 1)(0 - 1)(0 + 2)

16 = 2a(-4)(-1)(-1)

16 = 2a × -4

16 = -8a

a = -2

Hence, the equation becomes y = -2 (x - 4)(x - 1)(x - 1)(x + 2).

On graphing the equation it can be seen that -

As x → -∞, f(x) x → -∞

As x x → ∞, f(x) x → -∞

Therefore, the polynomial equation is h(x) = -2 (x - 4)(x - 1)²(x + 2).

Three points can define the two distinct vectors AB and AC (A, B, and C). The two vectors' cross product, which they both lie on, may be utilized as the plane's normal.

It is logical to assume that this is the case since a plane contains precisely two linearly independent vectors since it has a dimension of two. If the three points were collinear, there wouldn't be two linearly independent vectors; instead, the origin and tips of the two vectors are the three points.

The three points that make up a plane in a three-dimensional space can be used to define it as long as they are not on the same line. On a plane, there exist at least three non-collinear points.

Answer:

y=-2x+5

Step-by-step explanation:

First, solve the equation for one of the variables in the pair of equations to be solved using substitution method x = 2/13, y = 52

The substitution method is one algebraic approach to solving a linear system. By substituting one y-value for another, the substitution method works. We will illustrate this with an example. Since y = y, we can use y in the first equation instead of the second one.

                                      4x+2y=10⋅2x=26+2y

Take the first equation, for example. For a result of 20, multiply 10 by 2.

                                     4x+2y=20x

20 x both sides should be subtracted.

                                    4x+2y−20x=0

Get 16x by combining 4x and 20x.

                                  −16x+2y=0

The second equation is an example. For a result of 20, multiply 10 by 2.

                                      20x=26+2y

From both sides, subtract 2y.

                                          20x−2y=26

First, solve the equation for one of the variables in the pair of equations to be solved using substitution. Replacing that variable in the other equation with the result follows.

                                       −16x+2y=0,   20x−2y=26

By placing x on the left side of the equal sign, isolate x from one of the equations and solve it for x.

                                                −16x+2y=0

In the equation, deduct 2y from both sides.

                                     −16x=−2y

Subtract 16 from both sides.

                                          x= − 16/ 1(−2)y

16 divided by 2y is the answer.

                                         x= 8  / 1 y

The second equation, 20x2y=26, should now read 8 y instead of x.

                                  20×( 8 /1  )y−2y=26

multiply 20 times 8 y.

                          2  / 5 ​ y−2y=26

Boost 2y by 2.5 years.

                                 2 /1  y=26

2 times both sides will give you y=52.

In the formula x = 81y, change y to 52. You can solve for x directly because the resulting equation only has one variable.

                                        x= 8 /1  ×52

52 x 8 /1 is the multiplication.

In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is the best one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is not real. this text is ready triangles in Euclidean geometry, and in particular, the Euclidean plane, except wherein otherwise stated.
