Answer:

x = 1

Step-by-step explanation:

8 - 2x = -8x + 14

-2x + 8x = 14 - 8

6x = 6

x = 1

x=1 is the solution of the equation 8 - 2x = -8x + 14

Two or more expressions with an Equal sign is called as Equation.

The given equation is 8 - 2x = -8x + 14

x is the variable in the equation

Plus and minus are the operators

We have to solve for x

Take the variable terms one side and constants on other side

8x-2x=14-8

6x=6

Divide both sides by 6

x=1

Hence, x=1 is the solution of the equation 8 - 2x = -8x + 14

Answer:

She can bake 8 dozen cookies in 112 minutes.

Step-by-step explanation:

70/5 =14

112/14= 8

Density of fresh egg = 1.2 g/cm³.

Density of spoiled egg = Density of fresh egg   - 0.3 g/cm³.

Density of spoiled egg =( 1.2 - 0.3 ) g/cm³ = 0.9 g/cm³.

Now, it is given that any object with density less than 1 g/cm³ will float on water.

To tell whether an egg is spoiled or not using water. We should drop egg in water if it float then it is spoiled else it is fresh.

Hence, this is the required solution.

Answer:

First of all, <F is 63 degrees because of sum of angles in a triangle is equal to 180.

We know that the biggest angle in a triangle is always opposite the biggest side in a triangle, and vice versa. So, you can say that since <E is the smallest angle, the side opposite to it, side FD, is the shortest. Using just that, you can eliminate all options except the first and fifth. Now, <F is the second largest after that, and it's opposite to side DE. That piece of information helps you decide that the answer is Option Five (even though it's not numbered).

The option: FD<DE<EF

Answer:

This is a function

Step-by-step explanation:

This is a function because x is not repeated in any of the pairs. As long as x doesn't repeat, it is a function. y can repeat, but not x.

Answer:

Kelsey must produce 34 more pendants.

Step-by-step explanation:

Giving the following information:

Fixed costs= $200

Unitary variable cost= $7.8

Selling price per unit= $13.5

Desired profit= $50

To determine the number of units to be sold, we need to use the break-even point in units formula.

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point in units= (200 + 50) / (13.5 - 7.8)

Break-even point in units= 250/5.7

Break-even point in units= 43.86 = 44

Kelsey must produce 34 more pendants.

Step-by-step explanation:

Given the data:

Practice throws(X) : 4 10 6 15 0 7 11

Free throws(Y) : 8 23 9 34 5 11 27

Using the online linear regression calculator :

ŷ = 2.1559X + 0.3912

2.1559 = slope

0.3912 = intercept

X = independent variable ; y = dependent variable

The Coefficient of determination (R²) = 0.9506² = 0.9036

Quadratic model : y = 0.0961x²+0.7138x+3.8031

Coefficient of determination(R²) = 0.9739² = 0.9485

Exponential model:

a*b^x

Coefficient of determination (R²) = 0.9753² = 0.9512

The exponential model fits the data best.

Step-by-step explanation:

Hi, it seems the question is not complete, therefore I'll create an example tailored to the concept of the question you are asking.

1. Cumulative property can be used to change the order of addends and the result remains the same. Therefore the law states that, if a and b are real numbers, then a + b = b + a

Think about adding two numbers, such as 7 and 2.

7 + 2 = 9

2 + 7 = 9

The results are the same.

Notice, the order in which we add does not matter.

2. Associative property, this can be used to regroup addends and the result remains the same: the law states that, if a, b and c are real numbers, then

(a + b) + c = a + (b + c).

Think about three numbers, 4, 3 and 2

(4 + 3) + 2 = 7 + 2 = 9

4 + (3 + 2) = 4 + 5 = 9

The results are the same, notice that the regrouping did not change the final result.

Thank You This Helped Alot!

Answer:

Part A:

Y=959.006x=33366.667     (MEN)

Y=909.527x=25823.2     (WOMEN)

To simplify/find value of x: (SUBTRACT)

Y=959.006x=33366.667  

Y=909.527x= 25823.2    

After subtracting you should get:

Y=49.479x+7543.467

Answer:

The probability is  [tex]P(900 < X < 1100) = 0.358102[/tex]

Step-by-step explanation:

From the question we are told that

   The  population mean is  [tex]\mu = \$ 1130[/tex]

    The standard deviation is  [tex]\sigma = \$ 150[/tex]

Generally the probability that the gas bill will be between $900 and  $1100 is mathematically represented as

      [tex]P(900 < X < 1100) = P(\frac{900 - 1130 }{150 } < \frac{X - \mu}{\sigma } < \frac{1100 - 1130 }{150 } )[/tex]

=>  [tex]P(900 < X < 1100) = P(-1.533 < \frac{X - \mu}{\sigma } < -0.2 )[/tex]

Generally [tex]\frac{X - \mu}{\sigma } = Z (The\ standardized \ value \ of \ X)[/tex]

So

    [tex]P(900 < X < 1100) = P(-1.533 < Z< -0.2 )[/tex]

   [tex]P(900 < X < 1100) = P( Z< -0.2 ) - P(Z < -1.533)[/tex]

From the z  table  

     [tex]P(Z < -0.2 ) = 0.42074[/tex]

and

     [tex]P(Z < -1.533) = 0.062638[/tex]

So

     [tex]P(900 < X < 1100) = 0.42074 - 0.062638[/tex]

=> [tex]P(900 < X < 1100) = 0.358102[/tex]

Answer:

The age of  Hannah, Jeremy and Delmon are 20 years , 25 years and 25 years respectively

Step-by-step explanation:

Let H , J and D be the age of  Hannah, Jeremy and Delmon respectively.

We are given that Hannah noticed that the sum of their ages was 70.

H+J+D=70---1

Now we are given that Delmon, the youngest, burst out, "The difference between me and the oldest is more than 10 years!"

J-D>10

Now we are given that Hannah then realized that the difference between her age and each of the guys was more than 5 years.

So, D-H>5

J-H>5

D-H=5---2

J-H=5

So, D=J

Substitute in 1

2D+H=70 --3

Substitute the value of H from --3 in 2

D-70+2D=5

D=25

So, J = 25

Substitute values in 1

H+25+25=70

H=20

Hence the age of  Hannah, Jeremy and Delmon are 20 years , 25 years and 25 years respectively

I hope this is what you were needing the answer to!
