Answer:  The correct option is

(B) n and n + 2.

Step-by-step explanation:  We are given to select the correct pair of expressions that could represent consecutive odd numbers.

Let n and m be two consecutive odd numbers.

We know that

the difference between two consecutive odd numbers is 2.

So, we must have

m-n=2\\\\\Rightarrow m=n+2.

Therefore, if n is one odd number, then the next odd number is (n + 2).

Thus, n and n + 2  represents the pair of consecutive odd numbers.

(B) is the correct option.

Answer:

s(x)=\frac{0.2}{x+5}

Step-by-step explanation:

In 5 liters, there is 4% salt.

Lets find liters of salt.

First, converting 4% to decimal (dividing by 100):

4% = 4/100 = 0.04

0.04 * 5 = 0.2

So, there is 0.2 liters of salt.

Now, x liters of water is added to total, so total is now:

5 + x

The concentration of salt will be amount of salt divided by amount of salt water solution.

Amount of salt = 0.2 (as seen above)

Amount of new salt water solution = x + 5

So,

Concentration of salt in new solution is  \frac{0.2}{x+5}

2nd choice is right.

mash [69]

Answer:

y-4=-2(x+1)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(-4-4)/(3-(-1))

m=-8/(3+1)

m=-8/4

m=-2

y-4=-2(x-(-1))

y-4=-2(x+1)
