Answer:

the 3rd choice,   10x + 5, looks good

Step-by-step explanation:

a coefficient is the number in front of a variable , so that's 10

a constant is a number w/o a variable ...  so that's 5

I believe that the answer is 10x + 5.

Coefficents are also know as "multipliers". They pair with variables (in this case, that is x). Constants are simply numbers on their own.

Hope that makes sense.

Answer:

1053 m^3

Step-by-step explanation:

Pyramid top   1/3 * 9 * 9 * 12 = 324 m^3

Base  9 * 9 * 9  = 729 m^3

total  1053 m^3

The inequality 4/3|1/4x+3|<4 are Ox>-13 and x < -11 or Ox<-24 and x > 0

We can begin by isolating the absolute value on one side of the inequality:

4/3|1/4x+3|<4

|1/4x+3|<3/2

We can then split this inequality into two cases, one for when 1/4x+3 is positive and one for when it is negative:

1/4x+3>0: 1/4x+3>3/2, so multiplying both sides by 4, we get x>-13 and x<-11

1/4x+3<0: 1/4x+3<-3/2, so multiplying both sides by -4, we get x<-24 and x>0

So, the solution is: Ox>-13 and x < -11 or Ox<-24 and x > 0

The amount of money that you will have in eight years from today is $29,315.79 (rounded to 2 decimal places).

To find out the amount of money that you will have in eight years, you need to use the future value formula, which is:FV = PV × (1 + r)n

Where, FV = future value

PV = present value (initial investment) r = annual interest rate (as a decimal) n = number of years

First, you need to find the future value of the gift amount of $17,000 in two years.

Since it's a gift and not an investment, we can assume an interest rate of 0%.

Therefore, the future value would simply be:

PV = $17,000r = 0%n = 2 years

FV = $17,000 × (1 + 0%)2FV = $17,000

Now, you will loan that amount at 9.75% interest for six more years.

So, you need to find the future value of $17,000 after 6 years at an annual interest rate of 9.75%.

PV = $17,000

r = 9.75%

n = 6 years

FV = $17,000 × (1 + 9.75%)6

FV = $29,315.79

Therefore, the amount of money that you will have in eight years from today is $29,315.79 (rounded to 2 decimal places).

Answer:

S V W and if you rotate it the W would be an M

Step-by-step explanation:

The difference between the work rate of three persons and the work rate

of two people, gives the work rate of the third person.

Correct response:

The duration needed for Cory, Amanda, and Bryan together to finish painting the house = 9 days

The duration needed for Amanda and Bryan together to paint the house = 12 days

Required:

The number of days Cory will take to paint the house alone.

Solution:

Let t₁  represent the time it takes Cory to paint the house alone, let t₂

represent the time it takes Amanda to paint the house alone, and let t₃

represent the time it takes for Bryan to paint the house alone.

The work rate formula is presented as follows

\(\displaystyle \frac{1}{t} = \mathbf{ \frac{1}{t_1} +\frac{1}{t_2} +\frac{1}{t_3}}\)

Where;

t = The time it takes to paint the house together = 9 days

Which gives;

\(\displaystyle \frac{1}{9} = \frac{1}{t_1} +\frac{1}{t_2} +\frac{1}{t_3}\)

From the question, we have;

The time it takes Amanda and Bryan to paint the house together, is 12 gays, therefore;

\(\displaystyle \frac{1}{12} = \mathbf{\frac{1}{t_2} + \frac{1}{t_3}}\)

\(\displaystyle \frac{1}{9} = \frac{1}{t_1} + \frac{1}{12}\)

\(\displaystyle \frac{1}{t_1} = \frac{1}{9} -\frac{1}{12} = \mathbf{\frac{1}{36}}\)

a) The proportion of heads that  is represented in this sample is \(\bar{p}\)=0.583.

It is a parameter that describes a percentage number connected with a population. For example, the 2010 United States Census revealed that 83.7% of the American population was identified as not being Hispanic or Latino; the figure of.837 is a population proportion. In general, the population proportion and other population metrics are unknown. A census can be undertaken to establish the true value of a demographic metric, although it is generally impractical due to the expenses and time required.

A population proportion is typically computed using an unbiased sample statistic derived from an observational study or experiment.

Given that,

A coin is flipped 120 times, the number of heads we get are 70

a) The sample proportion is,

\(\bar{p}\)=No. of heads/No. of times the coin is flipped

The game described has multiple Nash equilibria.

In this game, each daughter has to choose an integer number of dollars between 1 and 50, and their goal is to maximize their own payoff. The total amount of money they can receive is limited to 51 dollars. If the total amount asked for exceeds 51, both daughters get nothing.

The Nash equilibria in this game occur when neither daughter can increase their payoff by unilaterally deviating from their chosen strategy. In other words, if both daughters have made their choices and neither has an incentive to change their choice, then it is a Nash equilibrium.

The number of Nash equilibria in this game depends on the choices made by the daughters. Since they do not coordinate and only care about their own payoffs, there can be multiple combinations of choices that result in Nash equilibria.

The missing angle in the triangle is as follows:

m∠ABC = 54 degrees

When lines segment intersect, angle relationships are formed such as vertically opposite angles,  adjacent angles etc.

Therefore, let's find m∠ABC.

Hence,

9x - 9 + 3x + 9 = 180 (sum of angles on a straight line)

12x  = 180

divide both sides of the equation by 12

x = 180 / 12

x = 15

Therefore,

m∠ABC = 3x + 9(Vertically opposite angles)

m∠ABC = 3(15) + 9

m∠ABC = 45 + 9

A schedule example that demonstrates a write-read conflict involving actions of transactions T1 and T2 on objects X and Y.  The write-read conflict occurs at step 2, when T2 reads the value of X after T1 has written to it, but before T1 has committed or aborted.

A write-read conflict occurs when one transaction writes a value to a data item, and another transaction reads the same data item before the first transaction has committed or aborted.
An example schedule with actions of transactions T1 and T2 on objects X and Y that results in a write-read conflict:
1. T1: Write(X)
2. T2: Read(X)
3. T1: Read(Y)
4. T2: Write(Y)
5. T1: Commit
6. T2: Commit
In this schedule, the write-read conflict occurs at step 2, when T2 reads the value of X after T1 has written to it, but before T1 has committed or aborted. This can potentially cause problems if T1 later decides to abort, since T2 has already read the uncommitted value of X.

Answer:

{x,y} = {2,-2}

Step-by-step explanation:

System of Linear Equations entered :

  [1]    7x + 3y = 8

  [2]    3x - 4y = 14

Graphic Representation of the Equations :

   3y + 7x = 8        -4y + 3x = 14  

Solve by Substitution :

// Solve equation [2] for the variable  x  

 [2]    3x = 4y + 14

 [2]    x = 4y/3 + 14/3

// Plug this in for variable  x  in equation [1]

  [1]    7•(4y/3+14/3) + 3y = 8

  [1]    37y/3 = -74/3

  [1]    37y = -74

// Solve equation [1] for the variable  y  

  [1]    37y = - 74  

  [1]    y = - 2  

// By now we know this much :

   x = 4y/3+14/3

   y = -2

The Equation of circle is (x-2)² +(y+ 8)² = 7²

The standard form of a circle with center (h, k) and radius r is given by the equation:

(x-h)²  + (y-k)² = r²

In this equation, (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

In this case, the center of the circle is (2, -8) and the radius is 7.

Plugging these values into the equation, we have:

(x- 2)² + (y- (-8))² = 7²

Simplifying further:

(x-2)² +(y+ 8)² = 7²

So, the equation in standard form for the circle with center (2, -8) and radius 7 is:

(x-2)² +(y+ 8)² = 7²

Alex gave Val three-tenths of a box of pencils, so she began out with three-fifths of a box.

To answer mathematical issues involving proportional relationships between various quantities, one can utilize the unitary method. In other words, given that two values are related in a constant ratio, it is helpful to determine the value of one if the value of another is known. With the unitary technique, a proportion is established based on how the two quantities relate to one another. The unknown amount can then be determined using the percentage.

given

Let's refer to Val's initial supply of pencils as the unknown portion of the box as x.

The three-tenths of a box of pencils Alex provided Val matched the problem statement. Following Alex's donation, Val had the following number of pencils:

x + 3/10

Val currently possesses nine-tenths of a box of pencils, which is also disclosed. We can therefore construct the following equation:

x + 3/10 = 9/10

By taking 3/10 off of both sides, we get at:

x = 9/10 - 3/10 = 6/10

Val thus started with 6/10 of a box of pencils. When we simplify this fraction, we obtain:

x = 3/5
