Answer:  First graph.

Step-by-step explanation:

Let C be the number of cookies, and B the number of brownies.

Each box has 2B = C     [2 brownies and 1 cookie]

Box  B  C

1       2   1

2      4   2

3      6   3

4      8   4

Graph 1 matches this data.  A line with a slope of 2.

Answer:

2

Step-by-step explanation:

2 is the rate of change for the graph because y/x=2 I am not sure wich unit of rate is larger because I cant see the equation

The proportionality constant will be equal to 2.

The ratio of two proportional values at a constant value is known as the constant of proportionality. The constant (commonly abbreviated k) related sums that increase or decrease simultaneously. It is the proportion between the values y and x.

Given table is below,

X      Y

2     4

3     6

4     8

5     10

6     12

The proportionality constant will be calculated as,

Y = KX

4 = K x 2

K = 4 / 2

K = 2

Therefore, the proportionality constant will be equal to 2.

I did synthetic division on the righthand side to make sure the answer was correct. Hope this helps :)

Answer:

[tex]\displaystyle x - 10[/tex]

Step-by-step explanation:

Since the divisor is in the form of [tex]\displaystyle x - c,[/tex]use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so do not forget it. Anyway, here is how it is done:

−1| 1 −9 10

↓ −1 10

________

1 −10 0 [tex]\displaystyle \hookrightarrow x - 10[/tex]

You start by placing the c in the top left corner, then list all the coefficients of your dividend [x² - 9x - 10]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient will be an [tex]\displaystyle x,[/tex]then you end it off with [tex]\displaystyle 10,[/tex]giving you the quotient of [tex]\displaystyle x - 10.[/tex]

Answer:

b + 35 = ??

Step-by-step explanation:

or something like that you would do b plus 35 to find how much he has now.

Answer:

x = 10°

Step-by-step explanation:

45 + 20x - 65 = 180°

=> -20 + 20x = 180°

=> 20x = 200

=> x = 10°

[tex]x = 3, x = -12[/tex]

Step-by-step explanation:

Hello!

We can factor the quadratic by grouping. We have to find two numbers that add up to 9 but multiply to -36.

The two numbers are 12 and -3. Expand 9x to 12 x and -3x.

The answer is Option B. x = 3 or -12.

Answer:

-2, as the expression is written

Step-by-step explanation:

It depends on how one interprets the expression.  The expression, as written, is:

4+24÷-6×2=

A fundamental rule in math is known as PEMDAS.  This acronym describes the order of operations that are to be followed when solving mathematical expressions.  PEMDAS stands for

P- Parentheses,

E- Exponents,

M- Multiplication,

D- Division,

A- Addition, and

S- Subtraction.

The use of parentheses is critical in math expressions, as we will see here.  

The are no parentheses in "4+24÷-6×2=."  So we will follow the steps are shown above:

Multiplication:  4+24÷-6×2 = 4+24÷-12

Division:    4+24÷-12 = 4+-2

Addition:  4+-2 = 2

The expression as written is equal to 2.

But if parentheses were included in the origianl proble, the answer might be different.  For example:  

(4+24)÷-6×2=

Parentheses:  (4+24)÷-6×2=  (28)÷-6×2=

Multiplication:  (28)÷-6×2= (28)/-12

Division:  (28)/-12 = -2.333 . . .

They start at -20 and descend so subtract the amount they descend from the starting value:

-20 -29 = -40

Ejemplo de un problema: 3m[tex]2^{2}[/tex]

-------------------------------------

Hallar el factor comun por agrupacion de terminos de los siguientes ejercicios

3m[tex]2^{2}[/tex] --> No factorizable, está en su forma más simple.

--------------------------------------------------------------------

Explicación: Solo puede factorizar, o simplificar, una ecuación o solo variables, si la variable que tiene un exponente tiene la misma base que otra variable, como x ^ 2 y x ^ 3, puede simplificarla ax ^ 5. Ahora, en este problema tenemos un 3, y 2 ^ 2, en el 2 ^ 2, 2 es la base y el otro número es 3, que definitivamente no es la misma base, por lo que no puede factorizarlo más, y deje la variable a lo largo.

~one variable linear equation

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

-4(2x - 5) = 3x - 13

= -8x + 20 = 3x - 13

= -8x + 20 - 3x = -13

= -8x - 3x = -13 - 20

= -11x = -13 - 20

= -11x = -33

= x = -33 ÷ -11

Answer:

To determine a cylinder's volume, you'll need to know its height and the radius of the circular base (the distance between the circle's center and its edge) at both the top and bottom. V = r 2 h is the formula, with V denoting volume, r denoting the radius of the circular base, h denoting height, and pi denoting the constant.

Answer:

$6.00

Step-by-step explanation:

Total amount of money = 0.25q + 0.1d

where q is the number of quarters and d is the number of dimes

The problem states we have 18 quarters: d = 18

And that there are 15 dimes: d = 15

Plugging it in we get

= 0.25(18) + 0.1(15)

= 4.5 + 1.5

= 6.0

Answer:

3n + 9 = -6

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the number  = x

3x + 9 = 2x - 6  Looks like you are going to get something negative here.

Subtract 2x from both sides.

3x - 2x + 9 = 2x - 2x - 6

x + 9 = -6    

Subtract 9 from both sides.

x + 9 - 9 = - 6 - 9

Combine

x = - 15
