Answer:

There are 5 books in 1 box

Step-by-step explanation:

It is quite easy to solve. You have to use division to figure out how many books go in each box. Our division equation will be: 20 ÷ 4 = ?

We will divide 20 by 4 and our answer is 5.

We can double-check our answer by doing multiplication. 5 x 4 = 20, leading us back to the original 20 books that are in boxes.

So, there are 5 books in each box.

Answer:

The conversion is given by [tex]3^{-2y+6} = -2x+1[/tex].

Step-by-step explanation:

Logarithmic Equation to Exponential Equation:

To realize the conversion of a logarithmic equation to an exponential equation, we need to understand the meaning of a logarithim. We have that:

[tex]\log_{a} b = c[/tex]

Means that:

[tex]b = a^c[/tex]

We are given the following equation:

[tex]\log_{3} (-2x+1) = -2y + 6[/tex]

It means that

[tex]3^{-2y+6} = -2x+1[/tex]

Which is the conversion.

The correct system of equations will be;

⇒ x + y = 9

And, $14x + $22y = $166

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Barbie spent $166 on clothes.

The cost of each pant = $22

The cost of each shirt = $14

Total number of items = 9

Now,

Let number of shirts = x

And, The number of pants = y

Since, Total number of items = 9

So, we can formulate;

⇒ x + y = 9

And, The cost of each pant = $22

The cost of each shirt = $14

So, We can formulate;

⇒ $14x + $22y = $166

Therefore, The correct system of equations will be;

⇒ x + y = 9

And, $14x + $22y = $166

Answer: Look down

Step-by-step explanation:

The y intercept changes. That’s it!

The shift is up or down. Positive goes up negative goes down.

The transform the graph of g(x) = In x in the graph of f(x) =In (-x) - 9.

The y-intercept changes.

We have given that,

g(x) = In x

The y-intercept changes

y-intercept changes it gives g(x).

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.

The shift is up or down

-x is shown the graph shift downward.

It gives the transform the graph of g(x) = In x in the graph of f(x) =In (-x) - 9.

Answer:

20 feet

Step-by-step explanation:

In this case, you'd use pythagoras's theorem (a^2 + b^2 = c^2)

The hypotenuse is always = c, so you'd set up the equation like this:

16^2 + 12^2 = c^2, where you're solving for c (to find out the length of the kite string)

This equation simplifies to 256 + 144 = c^2

which further simplifies to 400 = c^2

to solve for c, we square root both sides so the c is isolated:

[tex]\sqrt{400} = \sqrt{c}[/tex]

20 = c

so the length of the kite string is 20 feet

The required length of the kite string will be 20 feet.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

As per the question, we have to use Pythagoras's theorem

a² + b² = c²

Here hypotenuse = c,

Substitute the known values and we get

16² + 12² = c²,

Here c is the length of the kite string and simplifies the equation as:

256 + 144 = c²

c² = 400

c = √400

c = 20

Thus, the length of the kite string is 20 feet.

Answer:

The work will be finished in 10 days.

Step-by-step explanation:

Rashid can do a piece of work in 8 days

This means that each day he works, Rashid does [tex]\frac{1}{8}[/tex] of the work.

Tipu can finish in 12 days.

This means that each day he works, Tipu does [tex]\frac{1}{12}[/tex] of the work.

Each 2 days:

Each 2 days they work, the amount done is given by:

[tex]\frac{1}{8} + \frac{1}{12} = \frac{3 + 2}{24} = \frac{5}{24}[/tex]

Each 2 days, 5/24 of the work is done:

The number of periods of 2 days that is needed to finish the work(100% = 1 completed), is given by:

[tex]d = \frac{1}{\frac{5}{24}} = \frac{24}{5} = 4.8[/tex]

2*4.8 = 9.6

Rounding up

The work will be finished in 10 days.

For equal intervals changing in the independent variable, the corresponding dependent value does not change by equal differences, so it is not linear. which is the correct answer would be option (B).

A linear function is defined as an equation in which the highest exponent of the variable is always one.

The table is given in the question.

As per the given table,

The rate of change will be

During the first interval : (20-10)/(9-7) = 10/2

During the second interval : (30-20)/(11-9) = 10/2

During the third interval : (40-30)/(14-11) = 10/3

The corresponding dependent value does not vary by equal differences when equal intervals in the independent variable change, therefore it is not linear.

Hence, the correct answer would be an option (B).

Answer:

Step-by-step explanation:

I am assuming the question is asking which x value plugged into the function will give you a zero so

(-1)3 -8(-1)2 -23(-1)+30

so that simplyfiys to -1-8(1)+23+30

so that is -1-8+53

so -9+53

= 44

trying 3 we get

(3)3-8(3)2-23(3)+30

so that is 27 -72-69+30

and that is not zero

trying -10

we get

(-10)3-8(-10)2-23(-10)+30

which is -1000- 800+230+30

that is not zero so lastly trying  1 we get

(1)3-8(1)2-23(1)+30

which is 1-8-23+30

which is -7+7 which is zero
