A. (x + 4)(3x - 2)
B. (x − 2)(3x − 4)
C. (x + 1)(3x − 8)
D. (x − 1)(3x − 8)

Answers

Answer 1

Answer:

The Answer is D. (x - 1) (3x - 8)

Step-by-step explanation:

So, we start with \(3x^2 - 11x +8\).

First step is to break the expression into groups, by doing this, you get:

\(\left(3x^2-3x\right)+\left(-8x+8\right)\)

Next, factor out the 3x from  \(\left(3x^2-3x\right)\). By doing this, you should get:

3x(x - 1)

Then, factor out the 8x from  \(\left(-8x+8\right)\). By doing this, you will get:

-8(x - 1)

Last, factor out the common term, x - 1, When you do this, you get:

(x - 1) (3x - 8)

Hope this helps!

D.(x − 1)(3x − 8)

[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation in slope-intercept form? ³
O y = -2x - 1/6
O y = -2x + 7/6
O y = -2x + 5/12
O y = -2x - 11/12

[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation

Answers

Slope-intercept form is just solving for y in point-slope form

y - 2/3 = -2 (x - 1/4)

First you distribute the -2 because it is the first order of operation

y - 2/3 = -2x + 1/2

Then you add 2/3 on both sides because we want to isolate y

y = -2x + 1/2 + 2/3

Then we combine like terms

y = -2x + 7/6

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

The lengths of two sides of a right angled triangle are 20 cm and 30 cm.
Calculate the length of the third side, if it is:
(a) the hypotenuse
(b) not the hypotenuse

Answers

Answers:

Part (a)   10*sqrt(13) Part (b)   10*sqrt(5)

Those values are exact. They approximate to:

10*sqrt(13) = 36.0555

10*sqrt(5) = 22.3607

====================================================

Explanation:

Part (a)

If the unknown third side is the hypotenuse then we need to find the value of c when a = 20 and b = 30.

Apply the pythagorean theorem

a^2 + b^2 = c^2

20^2 + 30^2 = c^2

400 + 900 = c^2

1300 = c^2

c^2 = 1300

c = sqrt(1300)

c = sqrt(100*13)

c = sqrt(100)*sqrt(13)

c = 10*sqrt(13)  .... exact length

c = 36.0555 ...... approximate length

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

Part (b)

If the third side is not the hypotenuse then that must mean c = 30 is the hypotenuse as this side is larger than the 20 cm side. The hypotenuse is always the longest side.

Let a = 20 be the known leg. Let's find the other unknown leg b using the pythagorean theorem.

a^2 + b^2 = c^2

20^2 + b^2 = 30^2

400 + b^2 = 900

b^2 = 900-400

b^2 = 500

b = sqrt(500)

b = sqrt(100*5)

b = sqrt(100)*sqrt(5)

b = 10*sqrt(5) ..... exact length

b = 22.3607 .......  approximate length

10 students are watching a 2 hour and 42 minute long movie. Let S represent the number of students and M represent the number of minutes in that movie. If a different movie is 1 hour and 31 minutes, how many students are watching it?

Answers

If 10 students are watching a 2 hour and 42 minute long movie.  6 students are watching the second movie.

How many students are watching it?

We can use proportions to solve this problem. Let's start by finding the total number of minutes in the first movie:

M = 2 hours x 60 minutes/hour + 42 minutes = 120 minutes + 42 minutes = 162 minutes

Now, we can set up a proportion to find the number of students watching the second movie:

S/M = S'/M'

where S is the number of students watching the first movie (which we know is 10), M is the number of minutes in the first movie (162), S' is the number of students watching the second movie (which we want to find), and M' is the number of minutes in the second movie (91).

Substituting in the values we know and solving for S', we get:

10/162 = S'/91

S' = (10 x 91) / 162 = 5.62

Since we can't have a fractional part of a student, we need to round our answer to the nearest whole number. Therefore, approximately 6 students are watching the second movie.

Answer:

Step-by-step explanation:

a = \(\sqrt{12^2 -9^2} = \sqrt{144-81} = \sqrt{63}\)

We use the minus because we are searching a leg.

A leg is always shorter than the hypotenuse

Answer:

a = 7.9 or a = √63

Step-by-step explanation:

a² + b² = c²

(The two shorter sides of a triangle are always a and b while the longer side will always be c)

So, here the longer side of this triangle is 12 and the shorter sides are 9 and a (unknown).

The equation is: a² + 9² = 12²

But to find the value of a, the formula will be 12² - 9² = a²

12² - 9² = a²

144 - 81 = a²

63 = a²

the square root of 63 = 7.9    so that means a = 7.9

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.
