Here is a linear equation in x: 8x- 19 =-4-7x Is 5 a solution to the equation? That is,is x=5 a solution to the equation

Answers

Answer 1
Answer: 8x-19=-4-7x
8x+7x-19+19=-4+19-7x+7x
15x=15
(15x)/(15)=(15)/(15)
x=1
To prove:
8-19=-4-7
-11=-11
Therefore x≠5
Answer 2
Answer:

Answer:

X=5

Can someone help me rewrite this polynomial into a standard form

Answers

Answer:

x³ + 10x² + 1

Step-by-step explanation:

To rewrite the given polynomial in standard form, we need to arrange the terms in descending order of the exponent of the variable. The standard form of a polynomial is the form where the terms are written from highest to lowest degree.

The given polynomial is:

10x² + 1 - x³

To rewrite it in standard form, we first rearrange the terms in descending order of the exponent:

∴ x³ + 10x² + 1

Now the polynomial is in standard form.\hrulefill

Additional Information:

Polynomial: A polynomial is a mathematical expression that consists of variables (like x), coefficients (numbers), and non-negative integer exponents. The standard form of a polynomial is written with the terms in descending order of the exponents.

Degree of a polynomial: The degree of a polynomial is the highest exponent of the variable in that polynomial. In the given polynomial, the term with the highest degree is -x^3, so the degree of the polynomial is 3.

Exponent: The exponent of a term indicates the number of times the variable is multiplied by itself. For example, x^3 means x · x · x.

Coefficient: The coefficient is the number that multiplies the variable in each term. For example, in the term 10x^2, the coefficient is 10.

Descending order: When arranging the terms of a polynomial in descending order, we write the term with the highest degree first, followed by the term with the second-highest degree, and so on, until we reach the constant term (a term without a variable).
