PLEASE HELP!!! Find the equation of this line. All three answers please!!!
​

d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let p represent the bacteria population in thousand after d days.

Since each day, the bacteria population grows by a factor of 2, hence:

[tex]p=2^d[/tex]

Hence, d = log₂p represents a logarithmic function

The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

Step-by-step explanation:

Usando un sistema de ecuáciones, hay que Ezequiel tiene 11 años.

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

Sandro y Ezequiel son hermanos y el producto de sus edades es igual a la edad de su padre, o sea:

xy = z

Sandro es 8 años menor que Ezequiel, o sea:

x = y - 8.

La suma de su edad y la de su padre es igual a 36, o sea:

x + z = 36.

z = 36 - x

z = 44 - y

En el primer ecuácion:

xy = z

(y - 8)y = 44 - y

y² - 7y - 44 = 0

(y - 11)(y + 4) = 0

y - 11 = 0 -> y = 11.

Ezequiel tiene 11 años.

Using sampling concepts, it is found that the correct option is given by:

D. Move-Em-Out because the sample is not biased.

It is when a group is taken from a population, and the data taken from the group can be taken to estimate the data for the entire population. A sample has to be representative of the population, that is, it has to avoid bias.

In this problem, the sample from Pack-and-Move was taken only from people who appeared in their commercials, meaning that the sample is biased, as these people are more likely to report high satisfaction, hence option D is correct.

Answer:

88%

Step-by-step explanation:

You start out by finding the number of questions she got correct

200 - 24 = 176 questions answered correctly

You then want to divide the number of question she answered correctly by the total number of questions there are.

176/200 or 176 ÷ 200 = 0.88

0.88 = 88/100 = 88%

Answer:

y= -7+3x

The slope of the line is 3 and the intercept on the y-axis is 7.

Step-by-step explanation:

The slope-intercept form of the equation of a line is y=mx+c, where "m" is the slope of the line and "c" is the intercept of the line on the y-axis.

To find the slope and intercept of 6x+2y=14, you should solve for "y".

From the equation we get;

2y=-6x=14 or dividing each side by 2, we'll get y=3x+7.

Answer:

60 km/hr.

Step-by-step explanation:

When Dad caught up the the time he had been  driving was 4 hours and the time Mom had been driving was 1 + 4 = 5 hours.

They both drove the same distance, d km.

For Dad:

speed = d / time

75 = d / 4

d = 75 * 4 = 300 km.

Mom took 5 hours to travel this distance, so

Mom's speed was 300 / 5 = 60 km/hr.

Step-by-step explanation:

It is given that Sylvia sells x number of bottles and Sam sells three times as many bottles as Sylvia sold to his co-workers.

So, number of bottles Sam sold is 3x.

It is also given that, number of remaining bottle Sylvia and Sam have same.

So,

24 - x = 36 - 3x

3x - x = 36 - 24

2x = 12

x = 6

Therefore, Sylvia sells 6 bottles.

Hence, this is the required solution.

Work Shown:

|3x+12| = 18

3x+12 = 18 or 3x+12 = -18

3x = 18-12 or 3x = -18-12

3x = 6 or 3x = -30

x = 6/3 or x = -30/3

x = 2 or x = -10

The rule used in step 2 is the idea that if |x| = k, for some positive number k, then x = k or x = -k. One equation breaks into two separate ones. From there we solve each equation for x as normal. Follow PEMDAS in reverse, undoing each operation, to isolate x.

If you're curious why the absolute value breaks into two parts, consider something like |x| = 7. This means x is 7 units away from zero on a number line. There are two possible locations where x could be: 7 and -7. This is one example showing why we get two different results. The same applies to our equation as well, just it's a bit more complicated.

The set that represents a Pythagorean triple  is B: 33, 44, 55

A Pythagorean triple consists of three positive integers such that the square of the larger one of them is equal to the sum of the squares of the other two .

Let (a, b, c) represents a Pythagorean triple where a, b, c  are positive integer and a is the larger one  then a² = b² + c²

For A: 27 ,38, 42

Let a = 42 , b= 38 ,c= 27

⇒a² = 42² = 1764

and b² + c² =  38² + 27² = 1444 + 729 = 2173

∴a² ≠ b² + c²

Thus , A: 27 ,38, 42 is not a Pythagorean triple

For B: 33 ,44, 55

Let a = 55 , b= 33 ,c= 44

⇒a² = 55² = 3025

and b² + c² =  33² + 44² = 1089 + 1936 = 3025

∴a² = b² + c²

Thus , B: 33 ,44, 55  is a Pythagorean triple

For C: 35 ,38, 42

Let a = 42 , b= 35 , c= 38

⇒a² = 42² = 1764

and b² + c² =  35² + 38² = 1225 + 1444 = 2669

∴a² ≠ b² + c²

Thus ,   C: 35 ,38, 42 is not a Pythagorean triple

For D: 68 ,72, 81

Let a = 81 , b= 68 , c= 72

⇒a² = 81² = 6561

and b² + c² =  68² + 72² = 4624 + 5184 = 9808

∴a² ≠ b² + c²

Thus ,  D: 68 ,72, 81  is not a Pythagorean triple

Therefore, Only set B: 33, 44, 55 represents a Pythagorean triple.

Step-by-step explanation:

4x15=60

60-30=30

2x15=30

Answer:

Option C is the correct answer.

Step-by-step explanation:

We have been given that a and b are parallel to each with a straight angle.

If a and a are parallel, then angle suspended by a and b will be equal to each other. It is because of Alternate angle of triangle.

Let's head to the question.

According to the above statement, we have the following equation.

2x°= 4x -30°

0r, 2x° - 4° = -30°

0r, -2x° = -30

0r, 2x° = 30°

0r, x = 30°/2°

0r, x = 15°

Hence, x = 15° will show that lines a and b are parallel.

Answer: one CD cost $12 and  one DVD cost $15 .  

Step-by-step explanation:

In this situation we will represent the cost o one CD by x and the number of  one DVD by y.  Four CDs  plus five DVDs cost 123  so we will represent it by the equation  4x + 5y = 123  

The same or the second part of the statement. 2 CDs plus 4 DVDs cost $84  so we will also represent that by the equation , 2x + 4y = 84

Since we have two equations we will use it to solve or x and y using the elimination method.

4x + 5y = 123

2x + 4y = 84         Multiply the down equation by -2 to eliminate the x variable.

-2(2x + 4y ) = -2(84)

-4x -8y = -168    

We will now have the new equations ,

4x + 5y = 123

-4x - 8y = -168    Add both equations to      

      -3y = -45  

        y= 15  

This means each DVD cost $15 .

Now we will now have to solve for x by plotting in the value of y into the equation .

4x + 5(15) = 123

4x + 75 = 123

      -75     -75

4x = 48  

x = 12        

This also means that  one CD cost $12.
