The expression 3r - 6 can be written as _____. 3(r - 2) 3(r - 6) 3(3r - 6).

Answers

Answer:

The expression 3r - 6 can be written as 3(r - 2)

Step-by-step explanation:

We know that 3r-6=3(r-2) because 3*r is the same as 3r and we know that 3*-2 is -6 hence making them equal. And to check it we know that 3r-6 is equal to 3r-6.

CD is a line parallel to AB and passes through the point (3, 5).

c. Find the equation of the line CD

Answers

Answer:

y=5/3x+b

Step-by-step explanation:

Supposing CD uses the equation y=mb (meaning CD passes through the origin) and passes through (3,5), we then know the slope if 5/3 and the y intercept is 0. We can then write CD's equation as y=5/3x+0, or just y=5/3x.

So if AB is parallel to CB, then their equation is y=5/3x+b, as we don't the y-intercept yet.

Answers

The table is an illustration of a linear function

9. The student's rate

Take any two points from the table

[tex](x,y) =\{(1,644)\ (4,500)\}[/tex]

The rate is then calculated using:

[tex]Rate = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

This gives

[tex]Rate = \frac{644 -500}{1-4}[/tex]

[tex]Rate = \frac{144}{-3}[/tex]

[tex]Rate = -48[/tex]

The statement that the student reads at a rate of 48 pages per hour is true

10. The pages in the novel

From the table, there are 644 pages left, after the student read for 1 hour.

This means that there are more than 644 pages in the novel.

The statement that the number of pages in the novel is 644 is false

11. The linear equation

This is calculated as:

[tex]y = Rate(x -x_1) + y_1[/tex]

So, we have:

[tex]y = -48(x -1) + 644[/tex]

[tex]y = -48x +48 + 644[/tex]

[tex]y = -48x +692[/tex]

The statement that the situation can be represented by the  equation y = -48x + 692 is true

Step-by-step explanation:

to find the measure of angle X we must first find y

An exterior angle of a triangle is equal to the sum of the opposite interior angle

angle wyz is an exterior angle and the opposite interior angles are w and x

this means that angle wyz = angle w + angle X

if angle wyz = 52 , angle X = 3y and angle w = 4y-4 then 52 = 3y + 4y - 4

note that we just created an equation that we can use to solve for y

we now solve for y using the equation we just created

52 = 3y + 4y - 4

combine like terms

52 = 7y - 4

add 4 to both sides

56 = 7y

divide both sides by 7

we're left with y = 8

Now to find the measure of angle X we simply plug in the value of y into 3y because angle X = 3y

angle X = 3y

y = 8

angle X = 3(8)

multiply 3 and 8 to get 24

angle X = 24

Mike wants to fence in part of his backyard. He wants the length of the fenced-in area to be at least 20 feet long, l ≥ 20. He has 200 feet of fencing. The inequality that models the possible perimeter of the yard is 2l 2w ≤ 200. Which are possible dimensions for Mike’s backyard? Check all that apply. W = 50 ft; l = 10 ft w = 10 ft; l = 50 ft w = 20 ft; l = 60 ft w = 90 ft; l = 30 ft w = 50 ft; l = 40 ft.

Answers

The inequality that models the possible perimeter of the yard is 2(l + w) ≥ 200

The possible dimension of the width is 90 feet

The formula for calculating the perimeter of the fence is expressed as:

P = 2(l + w)

l is the length of the fencew is the width of the fence

If he has 200 feet of fencing, then:

2(l + w) ≥ 200

If the length of the fenced-in area to be at least 20 feet long, the equation becomes:

2(20 +w) ≥ 200

40 + 2w ≥ 200

2w ≥  200 - 40

2w≥ 160

w≥  80

Hence the possible dimension of the width is 90 feet

Find the sum of all solutions to the equation $3x(x+4) = 135$.

Answers

Answer:

-4

Step-by-step explanation:

3x(x + 4) = 135

3x² + 12x = 135

3x² + 12x - 135 = 0

On dividing by 3

x² + 4x - 45 = 0

x² + (9x - 5x) - 45 = 0

x² + 9x - 5x - 45 = 0

x(x + 9) - 5(x + 9) = 0

(x + 9)(x - 5) = 0

x = 5 & -9

Sum = -9 + 5

Sum = -4

The sum of the solutions of the given quadratic equation will be -4.

What is a quadratic equation?

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

As per the given equation,

⇒ 3x(x + 4) = 135

Multiply the 3x as,

3x² + 12x = 135

3x² + 12x - 135 = 0

Divide the above equation by 3 as

3x²/3 + 12x/3 - 135/3 = 0

x² + 4x - 45 = 0

x² + 9x - 5x - 45 = 0

x(x + 9) - 5(x + 9) = 0

(x - 5)(x + 9) = 0

x = 5 and x = -9

Therefore the sum will be -9 + 5 = -4

Hence "The total of the quadratic equation's answers will be -4".

Robin currently has 50 subscribers on her You Tube channel, and Dimitri currently has 17 subscribers. Robin gains 4 subscribers every week, while Dimitri gains 7 subscribers each week.
Part A: Set up a system of equations to shows each person's subscribers. (2 points)
Part B: After how many weeks will Robin and Dimitri have the same number of subscribers? (1 point)
Part C: How many subscribers will Robin and Dimitri have when their subscriber count is equal? (1 point)

Answers

We want to write and solve a system of equations to model the given situation.

The answers are:

A)

y =  50 + 4*x

y = 17 + 7*x

B) after 11 weeks.

C) 94 subscribers.

First, we must find the two linear equations, we know that Robin has 50 subscribers and she gets another 4 per week.

Then for Robin, we can write:

y = R(x) = 50 + 4*x

The equation that models the number of subscribers that Robin has at week x.

Dimitri at the moment has 17 subscribers and wins 7 per week, then his equation is:

y = D(x) = 17 + 7*x

A) Then the system of equations is just:

y =  50 + 4*x

y = 17 + 7*x

B) Now we must solve the system.

Notice that in both equations we have y isolated, then we can write:

50 + 4*x = y = 17 + 7*x

50 + 4*x =17 + 7*x

Now we can solve this for x:

50 + 4*x =17 + 7*x

50 - 17 = 7*x - 4*x

33 = 3*x

33/3 = 11 = x

This means that at week 11 they will have the same number of subscribers.

C) To get this we just need to evaluate any one of the two linear equations in x = 11

D(11) = 17 + 7*11 = 94

Both of them will have 94 subscribers.

the numbers 1 to 9 are randomly arranged to form a 9-digit number. what is the probability that the number obtained is divisible by 18?
(please write the solution)

Answers

Answer:

Hence the probability that the number is divisible by 18 is 4/9 or approx. 0.4444. or even 44.4%

Step-by-step explanation:

If we have 9 digits 1–9 placed randomly to form a 9-digit number without repetition and we want the probability of that number is divisible by 18, then we only need to look at the fact if it is divisible by 18, then it is also divisible by 2 and 9. Adding the digits 1–9 would give us the following (including checking for divisibility by 9):

(9 x 10)/2 =90/2 = 45

45÷9=5

By divisibility of 9, if the sum of the digits is divisible by 9, then the original number itself is divisible by 9. Since the number 45 is divisible by 9, we know that all the possible 9-digit numbers will be as well. The only thing we would have to look at is if it is even since the number has to be divisible by 2. 

There are 9 digits of which 4 are even (2, 4, 6 or 8).

So the probability that the number is divisible by 2 is 4/9.

Hence the probability that the number is divisible by 18 is 4/9 or approx. 0.4444.

Using the Central Limit Theorem, it is found that the shape of [tex]\bar{x}[/tex] is approximately normal.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, the distribution is not normal, however the sample size is of 100 > 30, hence the Central Limit Theorem is applicable and the shape of [tex]\bar{x}[/tex] is approximately normal.
