Subtracting a polynomial has the same result as adding its additive inverse.

1 answer:

7 0

The answer is true...

Why?

Let's take (2x) as a simple polynomial. Subtracting 2x from 2x is one thing, then adding it's inverse, (-2x) yields the equation to 0. This is why it is true...

Hope this helps!! Please give me brainliest!

Solve the following inequality for w then simplify <br> -w+9>6w+8

Alla [95]

Answer:

$\displaystyle (-\infty,\frac{1}{7})$

Step-by-step explanation:

<u>Inequalities</u>

To solve the inequality:

$-w+9>6w+8$

We need to perform the required operations on both sides of the inequality to have the variable w isolated.

First, we subtract 9:

$-w+9>6w+8$

$-w>6w+8-9$

Subtracting 6w:

$-w-6w>+8-9$

Operating:

-7w>-1

Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:

$\displaystyle w$

Operating:

$\displaystyle w$

Solution:

$\mathbf{\displaystyle (-\infty,\frac{1}{7})}$

Combine the like terms to create an equivalent expression: <br> 2s+(−4s)=?

Sergeeva-Olga [200]

Answer:

$2s+\left(-4s\right)=-2s$ is the equivalent expression as $2s+\left(-4s\right)$ is equal to $-2s$ .

Step-by-step explanation:

Considering the expression

$2s+\left(-4s\right)$

As we know that

Like terms are said to be the terms which hold the same variables raised to the same power.

For example, $3x$ and $2x$ are like terms as they contain the same variable $x$ raised to the same power.

Lets solve the expression

$2s+\left(-4s\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$2s-4s$

$\mathrm{Add\:similar\:terms:}\:2s-4s=-2s$

$-2s$

Therefore,

$2s+\left(-4s\right)=-2s$ is the equivalent expression as $2s+\left(-4s\right)$ is equal to $-2s$ .
