Answer:

The answer is (4) $2x+x^{2} +4x^{3}$ .

Step-by-step explanation:

A leading coefficient is the coefficient of the term of highest degree in a given polynomial.

A degree of a polynomial is the largest exponent on one of its variables (for a single variable), or the largest sum of exponents on variables in a single term (for multiple variables).

The answer can be found when the polynomial is rearranged into standard form, and the standard form of the polynomial will look like $4x^{3}+x^{2} +2x$ . A polynomial is in standard form when the term with the highest degree is placed first, followed by the term which has the next highest degree, and so on.

Once the polynomial is in standard form, the leading coefficient is 4 and has a degree of 3. Thus, causing (4) $2x+x^{2} +4x^{3}$ to be the answer.

Answer:

choice 4

Step-by-step explanation:

It's not that hard if you understand once you get past the fancy words

degree= largest exponent

so if something has a degree of 3 we know that the highest exponent is 3

Coeficcent= thing multipllying x

in this case it's 4 which means the number we are looking for is 4x³

Onlyanswer choice 4 meets these criteria

Which operation is going to be performed first <br>3÷2+(10-2×4)

sergejj [24]

Answer:

parenthesis

Step-by-step explanation:

Hello!

To know what the order of operations is we go by PEMDAS

Parenthesis then Exponents then multiplication and division from left to right then addtion and subtraction from left to right.

Since parenthesis are in this equation we would do those first

The answer is parenthesis

Hope this helps!

Solutions to -8x + 5 less than or equal to 11

Vilka [71]

Answer:

$x\geq -\frac{3}{4}$

Step-by-step explanation:

$-8x+5\leq 11\\\\1. -8x\leq 11-5\\ -8x\leq 6$

Isolate the parts of the equation with the x variable

$2. \frac{-8}{-8} x\geq\frac{6}{-8} \\x\geq -\frac{3}{4}$

When you divide or multiply by a negative number in inequalities, you must flip the sign of the inequality.

Find a polynomial function of least degree having only real coefficients, a leading coefficient of 1, and roots of 2-√6 , 2+ √6

horsena [70]

Answer:

$x^{4} -18x^{3}+104x^{2} -172x-100$

Step-by-step explanation:

The 3 roots are given out of which 2 are real and 1 is imaginary. For a polynomial of least degree having real coefficients, it must have a complex conjugate root as the 4th root. Therefore, based on 4 roots, the least degree of polynomial will be 4. Finding the polynomial having leading coefficient=1 and solving it based on multiplication of 2 quadratic polynomials, we get:

$\\\\x_{1} = 2-\sqrt{6} \\x_{2} = 2+\sqrt{6} \\x_{3}=7-i \\x_{4}=7+i \\\\P(x)=1(x-x_{1})(x-x_{2} )(x-x_{3} )(x-x_{4} ) \\\\=(x-(2-\sqrt{6}))( x-(2+\sqrt{6} )) (x-(7-i))( x-(7+i))\\=((x-2)+\sqrt{6})( ( x-2)-\sqrt{6} ) ((x-7)+i)( (x-7)-i)\\=((x-2)^{2} -(\sqrt{6} )^{2} )((x-7)^{2}-(i)^{2})\\=(x^{2} -4x-2)(x^{2} -14x+50)\\=x^{4} -18x^{3}+104x^{2} -172x-100\\$

URGENT!!!!!! Find the value of q in the following system so that the solution to the system is——

valkas [14]

<h3>Answer: Q = 8</h3>

====================================================

Explanation:

The left hand side of the first equation is x-3y

The left hand side of the second equation is 2x-6y = 2(x-3y). Note how it's simply double of the first expression x-3y

If we multiply both sides of the first equation by 2, we get

x-3y = 4

2(x-3y) = 2*4

2x-6y = 8

Meaning that 2x-6y = 8 is equivalent to x-3y = 4. Both produce the same line leading to infinitely many solutions. Each solution will lay along the line x-3y = 4.

We can say each solution is in the set {(x,y): x-3y = 4}

Which is the same as saying each solution is of the form (3y+4,y)
