Answer:

Step-by-step explanation:

The given expression is

$-k-(-8k)$

We need to find the simplified form of the given expression.

Like terms: The terms which have same variables of same degree and known as like terms. For example: 2x and 4x are like terms.

The given expression can be rewritten as

$-k+8k$

On combining like terms we get

$(-1+8)k$

$7k$

Therefore, the equivalent expression of the given expression is 7k.

Find f(−5) if f(x)=|x+1|. Type a numerical answer in the space provided. Do not type spaces in your answer.

marin [14]

<h3>Answer: 4</h3>

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

Work Shown:

f(x) = |x+1|

f(-5) = |-5+1| .... x is replaced with -5

f(-5) = |-4|

f(-5) = 4
