Answer:

x≥-6

Step-by-step explanation:

The domain is every value of x.  Since the function does not include any values of x less than -6, x≥-6 is the domain.

The inequality which represents the domain of the function is y>=6 . Hence, option A is correct.

The domain of a function is the set of all possible input values. In other words , we could say the x - values for which valid y-values are obtained.

From the graph, the line depicts , valid y- values starting from -6 and higher.

Hence, the values include ;

Therefore, the correct option is A.

Answer: B) 4 bins

Step-by-step explanation:

The criteria of divisibility are rules that serve to know if a number is divisible by another without having to perform the division.

A number is divisible by 3 (or 9) if and only if the sum of its digits is divisible by 3 (or 9).

5,272

5 + 2 + 7 + 2 = 16

1 + 6 = 7 →This number isn't divisible by 3, therefore 5,272 isn't divisible by 3

Divisibility by 5 is easily determined by checking the last digit in the number , and seeing if it is either 0 or 5. If the last number is either 0 or 5, the entire number is divisible by 5.

5,272 → the last digit is 2; isn't 0 or 5, therefore 5,272 isn't divisible by 5.

The basic rule for divisibility by 4 is that if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4

5,272

the last two digits are 72, and 72/4 = 18

72 is divisible by 4, therefore 5,272 is divisible by 4

Since 5,272 is divisible by 4, Michael can use 4 bins to organize the blocks, and he needs to put 5,272/4 = 1,318 blocks in each bin.

Correct choice is C) [tex]6x^3-22x^2+24x-8[/tex].

Step-by-step explanation:

Given that the dimensions of a box are x, 2x, and 3x.

Now each dimension is decreased by 2.

Then new dimensions of a box are (x-2), (2x-2), and (3x-2).

Now let's calculate the volume of the box which is given by

Volume = (Length) x (Width) x (Height)

[tex]=(x-2)(2x-2)(3x-2)[/tex]

[tex]=(2x^2-6x+4)(3x-2)[/tex]

[tex]=(2x^2-6x+4)(3x-2)[/tex]

Hence correct choice is C) [tex]6x^3-22x^2+24x-8[/tex].

Answer:

You can make 10 combinations.

Step-by-step explanation:

you can make 10 combinations because all you have to do is just add all the numbers then you get 10

We want to find the total number of combinations of outfits, given that we know the number of each type of clothes that you have.

Using basic counting, we will get that there are 30 different outfit combinations.

Let's see how to get that:

To count the total number of combinations, the first thing we need to find is the selections.

Here we have 3 selections:

Now we need to find the number of options for each one of these selections:

To get the total number of combinations, we just need to multiply all of these numbers of options, we will get:

3*2*5 = 30

This means that there are 30 different outfit combinations.

About the graph of the function option (B) the function is decreasing and option (D) the y-intercept is (0, 1) is the correct answer.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The graph of a function f is the set of all points in the plane of the form (x, f(x)).

For the given situation,

The function is  y=(1/3)^x.

Plot this function in the graph as shown below.

From the graph, the y-intercept is (0,1) and the function is decreasing function.

Answer:

(2.5,5)

Step-by-step explanation:

thats the answer

Answer:

The solution point is (2.5, 5)

Step-by-step explanation:

This is one of the very first steps you need to take in order to solve 2 equations with 2 unknowns. This does not require that you make any adjustments.

2x + y  =  10

-2x +2y = 5        Just add. The xs cancel.

3y = 15                Divide by 3

3y/3 = 15/3

y = 5

=========

Now use one of the equations (the top one is easier) to solve for x

2x + y = 10      Substitute y = 5

2x + 5 = 10      Subtract 5

2x +5-5 = 10-5  

2x = 5              Divide by 2

x = 2.5

The solution point is (2.5 , 5)

The polynomial 10x^3 - 35x^2 + 6x - 21 is factored using the grouping method to obtain (2x - 7)(5x^2 + 3).

To factor the polynomial 10x^3 - 35x^2 + 6x - 21 using the grouping method, we first look for a common factor in each group separately and then factor out the common binomial factor.

Split the polynomial into two groups: (10x^3 - 35x^2) and (6x - 21).

Factor out the greatest common factor from each group: 5x^2(2x - 7) and 3(2x - 7).

Now we have 5x^2(2x - 7) + 3(2x - 7). Since both terms have a common binomial factor of (2x - 7), we can factor this out: (2x - 7)(5x^2 + 3).

So, the factored form of the polynomial 10x^3 - 35x^2 + 6x - 21 using the grouping method is (2x - 7)(5x^2 + 3).

Answer:

C. 2x +5y = -15

Step-by-step explanation:

You want the form ax +by = c. To get that form, you need to put the x-term on the left (making sure its sign is positive) and the constant on the right.

Multiply by 5:

5y +35 = -2(x -10)

Eliminate parentheses:

5y +35 = -2x +20

Add 2x-35

2x + 5y = -15 . . . . . . corresponds to selection C

Answer:

D

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 6, - 8), thus

(x + 6)² + (y + 8)² = r²

The radius is the distance from the centre to a point on the circle

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)

r = [tex]\sqrt{(0+6)^2+(0+8)^2}[/tex] = [tex]\sqrt{36+64}[/tex] = [tex]\sqrt{100}[/tex] = 10

Hence

(x + 6)² + (y + 8)² = 100 → D
