Answer: B = 9


Step-by-step explanation:


16-b=7

Rearrange so we can subtract 16 by 7

16 - 7 = 9


Substituting 9 for b and making sure it's correct.

16 - 9 = 7

Answer:

9

Step-by-step explanation:

The first thing to do is to subtract 16 from both side of the equation:

16 - 16 - b = 7 - 16

The 16s on the left cancel out resulting in:

-b = -9

Think of the -b as -1(9). This is multiplication. By doing the inverse operation (division) we can get rid of the negative on the b. We will divide both sides by -1.

\frac{b}{-1} = \frac{-9}{-1}

This leaves a positive b. Since both parts of the right side of the equation are negative it becomes positive ( a negative divided by a negative is a positive).

The final answer is b= 9.

Check our work by plugging in the b value (9) into the original equation:

16 - 9 = 7

7 = 7 is true so we now we have the right answer.

Answer:

<em>The translation corresponds to a translation of 13 units to the right</em>

Step-by-step explanation:

<u>Translation of a Graph</u>

If the graph of

y=f(x) is translated a units horizontally, then the equation of the translated graph is

y =f(x - a)

The value of a is considered positive for translations to the right.

The parent function is

y = x

and the given function is

y = x - 13

The translation corresponds to a translation of 13 units to the right

The ratio of nonfiction books to fiction books in a library is 105 to 189. Which statement describes this relationship?
kolezko [41]

Answer: A)There are 5 nonfiction books for every 9 fiction books in the library.  

Step-by-step explanation: If you do the math you realize that there are clearly less nonfiction books than fiction books.

105/5=21 and after 21*9 lines up and to check your work than

5*21=105 and 9*21=189 it is not B because the smaller number 105 is in front of the ratio 105:189 and 5:9
