Answer:

-2

Step-by-step explanation:

Answer: -2

Step-by-step explanation: the y intercept is -2 because on the table x is at -2 and y is at 0 making that the origin for Y and the -2 according to graphs would intercept the origin. Thus making -2 the intercepting value for (Y)

Explanation:

Using a calculator shows that

We see that nearly all of the decimal values are terminating decimals. This means the decimals don't go on forever, so the decimals stop at some point.

Only 0.083333... goes on forever, so that's why 1/12 converts to a repeating decimal number.

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

A way you can determine this without a calculator is to use long division. Or you could use the idea that if the denominator has prime factors other than 2 and 5, then the decimal will repeat forever.

Note how the denominators of the fractions for choices B through E all have prime factors of either 2s only, 5s only, or a mix of 2s and 5s. This fact is why we have terminating decimals here.

In contrast, 12 has prime factorization 2*2*3. That 3 as a prime factor is why the decimal repeats forever.

The only fraction that converts to a repeating decimal number is 1/12.

Decimal is a fraction whose denominator is a power of ten and whose numerator is expressed by figures placed to the right of a decimal point.

Given is to find a fraction that converts to a repeating decimal number.

Repeating decimals are the decimals of the form -

2.7777...

2.34343434...

2.43434343....

Now, we have the fractions and their corresponding decimal numbers as follows -

Therefore, the only fraction that converts to a repeating decimal number is 1/12.

Answer:

d- all students from each grade

Step-by-step explanation:

Answer:

D, all students in each grade.

Step-by-step explanation:

If you did a random sample from the students in the speech club it will be biased because they will probably all say giving speeches because they are in the speech CLUB. You cannot do the teahcers because their answers will also be biased. If you do all the boys in each grade it will be biased only to what boys like and not girls or any other student in the grade. Therefore, using the process of elimination, the answer is D, you should take a random sample of all the students in each grade.

Answer:

7.17 by 7.17 by 3.58

Step-by-step explanation:

Since the rectangular box is square based, the total surface area is expressed as;

S = x²+2xh+2xh (the top is opened)

S = x² + 4xh ..... 1

x is the side length of the square

h is the height of the box

Also the volume V = x²h

Given V = 184

184 = x²h

h = 184/x² .... 2

Substitute 2 into 1;

S = x² + 4xh

S = x² + 4x(184/x²)

S = x² + 4(184/x)

S = x² + 736/x

Since we need a dimension that will minimize the surface area of the box then, dS/dx = 0

dS/dx = 2x -736/x²

0 = 2x -736/x²

multiply through by x²

0 = 2x³- 736

2x³ = 736

x³ = 736/2

x³ = 368

x = ∛368

x= 7.17 in

Since V = x²h

184 = 7.17²h

h = 184/7.17²

h = 184/51.4089

h = 3.58 in

Hence the dimensions of the box should be to minimize the surface area of the box are 7.17 by 7.17 by 3.58

Answer:

y = 42 - 6 x

Step-by-step explanation:The slope-intercept formula is:

y = m x + b,

or: y = b - m x, since the rate is negative.

For the 1st formula we have: y = 30 and x = 2

For the 2nd formula: y = 12 and x = 5 ( because: 5 = 2 + 3, or : 3 minutes later, which can be confusing  )

30 = b - 2 m

12 = b - 5 m

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

b = 30 + 2 m

12 = 30 + 2 m - 5 m

3 m = 18

m = 18 : 3 = 6

b = 30 + 2 * 6 = 30 + 12 = 42

y = 42 - 6 x

Answer:

Frazer is the 8kg and Tyler is 15 kg.

Step-by-step explanation:

Total 23kg. Take away the 7kg, that Tyler weighs more, is 16.

Half the 16 to get 8.

please mark as the brainliest

Tyler and frazer weigh a total of 23kg then Frazer weighs 8 kg and Tyler weighs 15 kg.

Now assume Frazer's weight as x.

According to the problem, Tyler is 7kg heavier than Frazer.

Hence, Tyler's weight will be x + 7.

Now We know that the total weight of both of them is 23 kg.

Therefore, the equation will be:

x + (x + 7) = 23

Simplifying the equation, we get:

2x + 7 = 23

Now, subtracting 7 from both sides of the equation, we get:

2x = 16

Dividing both sides by 2,

x = 8

So, Frazer weighs 8 kg.

Now, we can calculate Tyler's weight as:

x + 7 = 8 + 7 = 15 kg

Therefore, Tyler weighs 15 kg.

Answer:

y = 3x + 10

Step-by-step explanation:

Given that,

Slope = 3

y intercept = 10

We need to write an equation of a line.

The slope-intercept form of a linear equation is given by :  

y = mx + b

Where

m is slope and b is y-intercept

Putting all the given values,

y = 3x + 10

Hence, the required equation is "y = 3x + 10"

Answer:

Since length is three times, hence it is 6 inches.

let the width be x.

then, length= 3x

perimeter= 16 inches.

perimeter of a rectangle = 2( L+B)

2(3x+x)=16.

3x+x= 16÷2

4x= 8

x= 2

since length=3x

hence, 3×2= 6 inches

La función resultante es una función a trozos:

[tex]C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}[/tex]

Step-by-step explanation:

El coste total de la electricidad suministrada ([tex]C_{T}[/tex]), medida en pesos, es la suma del coste fijo ([tex]C_{F}[/tex]) y el coste variable ([tex]C_{V}[/tex]), medidas en pesos.

[tex]C_{T} = C_{F}+C_{V}[/tex] (1)

Ahora, tenemos que el coste fijo es $ 100 mensuales, así:

[tex]C_{F} = \$ \,100[/tex] (2)

Y el coste variable considera que se cobra 15 centavos por kilowatt-hora para los primeros 400 kilowatts-hora y 12 centavos por kilowatt-hora para cada kilowatt-hora que pase de 400 kilowatts-hora en el mes:

(i) Menos o igual que 400 kilowatts-hora:

[tex]C_{V} = 0.15\cdot x[/tex] (3)

Donde [tex]x[/tex] es la electricidad suministrada en kilowatts-hora.

(ii) Mayor que 400 kilowatts-hora:

[tex]C_{V} = 0.15\cdot (400)+0.12\cdot (x-400)[/tex]

[tex]C_{V} = 12+0.12\cdot x[/tex]

La función resultante es una función a trozos:

The answer is x= -5 1/4

Step-by-step explanation:

Let's solve your equation step-by-step.

2/3x−4 1/2=−8

Step 1: Simplify both sides of the equation.

2/3x+−9/2=−8

Step 2: Add 9/2 to both sides.

2/3x+−9/2+9/2=−8+9/2

2/3x=−7/2
