Answer:

C. 2x - 3(-3x - 4) = -21.

Step-by-step explanation:

y + 3x = -4

2x - 3y = -21

From the first equation y = -3x - 4.

Substituting this for y in the second equation, we have:

2x - 3(-3x - 4) = -21.

What is the value of this expression when m = 6? the difference of the product of 3 and m minus the quotient of m divided by 2

Anettt [7]

Answer:

Step-by-step explanation:

Expressing the sentence Mathematically ;

The product of 3 and m = 3m

Quotient of m divided by 2 = m/2

Hence, the expression becomes ;

3m - m/2 ; value of expression when m = 6

(3m - m/2) ; when m = 6

(3(6) - 6/2)

(18 - 3)

= 15

The polynomial p(x)=x^3-7x-6 has a non-factor of (x+1) rewrite p(x) as a product of linear factors.

In-s [12.5K]

Answer:

Using synthetic division suffices to answer your question:

Step-by-step explanation:

Synthetic division is the process by one reduces a large polynomial in your case $x^3-7x-6$ by a binomial in your case $(x+1)$ .

To do so one does the following:

$\begin{array}{cccccc}-1|& 1&0&-7&-6\\ & &-1&1&6 \\& 1&-1&-6&0 \end{array}$

Since we divided by a linear binomial it reduces the power by one which produces the following quadratic:

$(x^2-x-6)$

Which can be factored in the following, and I will provide the complete factorization as well:

$p(x)=(x+1)(x-3)(x+2)$
