Answer:

see explanation

Step-by-step explanation:

Given

2x³ - x² + 18x - 9 = 0 ( factor the first/second and third/fourth terms )

x²(2x - 1) + 9(2x - 1) = 0 ← factor out (2x - 1) from each term

(2x - 1)(x² + 9) = 0

Equate each factor to zero and solve for x

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

x² + 9 = 0 ⇒ x² = - 9 ⇒ x = ± 3i

The equation has 1 real solution and 2 complex solutions

x = [tex]\frac{1}{2}[/tex] ← real solution

x = ± 3i ← complex solutions

Answer:

-13/2

Step-by-step explanation:

slope is calculated as (y2-y1)/(x2-x1)

(x1, x2) is (1,6) and (y1,y2) is (3,-7)

doing (y2-y1)/(x2-x1) gives us ((-7)-6)/(3-1)

= -13/2

The slope between the points (1,6) and (3,-7) is calculated as -6.5 using the slope formula.

The slope between two points (1,6) and (3,-7) can be calculated using the slope formula: m = (y2 - y1) / (x2 - x1),

where (x1, y1) and (x2, y2) are the coordinates of the points.

In this case, substituting the values in, we get:

m = (-7 - 6) / (3 - 1) = -13 / 2 = -6.5.

Thus, the slope between the points (1,6) and (3,-7) is -6.5.

Answer:

The height of the building is [tex]1\frac{1}{4}\ feet.[/tex]

Step-by-step explanation:

Given:

Scale drawing is 1/4 inch: 1 foot.

The height of the building in drawing is 5 inches.

Now, to find the actual height of the building.

Let the actual height be [tex]x.[/tex]

The height of the building in drawing = [tex]5\ inches.[/tex]

The ratio of the scale drawing is [tex]\frac{1}{4}\ inch:1\ foot.[/tex]

So, [tex]\frac{1}{4}\ inch[/tex] is equivalent is 1 foot.

Thus, 5 inches is equivalent to [tex]x.[/tex]

Now, to get the actual height of the building by using cross multiplication method:

[tex]\frac{\frac{1}{4}}{1} =\frac{5}{x}[/tex]

[tex]\frac{4}{1} =\frac{5}{x}[/tex]

By cross multiplying we get:

[tex]4x=5[/tex]

Dividing both sides by 4 we get:

[tex]x=\frac{5}{4}[/tex]

[tex]x=1\frac{1}{4}[/tex]

Therefore, the height of the building is [tex]1\frac{1}{4}\ feet.[/tex]

Jason bought 38 stamps and 17 postcards

Solution:

Let "a" be the number of stamps bought

Let "b" be the number of postcards bought

The number of stamps was 4 more than twice the number of post cards

Therefore,

Number of stamps bought = 4 + 2(number of post cards)

a = 4 + 2b ------- eqn 1

Jason bought both 41 cent stamps and 26 cent postcards and spent $20.28

1 dollar is equal to 100 cents

Thus, $ 20.28 is equal to 2028 cents

Therefore, we frame a equation as:

[tex]41 \times a + 26 \times b = 2028[/tex]

41a + 26b = 2028 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 1

41(4 + 2b) + 26b = 2028

164 + 82b + 26b = 2028

164 + 108b = 2028

108b = 1864

[tex]b = 17.25 \approx 17[/tex]

Substitute b = 17 in eqn 1

a = 4 + 2(17)

a = 4 + 34

a = 38

Thus Jason bought 38 stamps and 17 postcards

The correct answer is E. Both functions are linear, only crossing the x-axis once and the y-axis once.

We can see from the graph that both Function A and Function B are straight lines. This means they are linear functions.

Linear functions also have only one x-intercept and one y-intercept. The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

The y-intercept for both Function A and Function B is at (0,0). The x-intercept for Function A is at (-2,0) and the x-intercept for Function B is at (1,0).

Therefore, both statements in choice E are true.

The other statements in the question are not true.

Choice A, Both functions have negative rates of change, is not true. Function A has a negative rate of change, but Function B has a positive rate of change.

Choice B, Both functions have the same rate of change, is not true, as discussed above.

Choice C, When graphed, Function A and Function B are parallel, is not true. Parallel lines would never intersect, but the two functions intersect at the origin.

Choice D, Function A has a greater rate of change than Function B, is not true. The slope of Function B is steeper than the slope of Function A, so Function B has a greater rate of change.

Answer:

12 months

Step-by-step explanation:

A company employs 72 workers. It plans to increase the number of employees by 6 per month.

Let x = number of months when the company increases the number of workers. Then in x months, the number of workers increases by 6x and the total number of workers will be (72+6x).

They plan to increase the number of workers until it has twice its current workforce. So

[tex]72+6x=2\cdot 72[/tex]

Solve this equation:

[tex]72+6x=144\\ \\6x=144-72\\ \\6x=72\\ \\x=12[/tex]

Answer:

They are not equivalent

Step-by-step explanation:

We want to determine if 1/2(4 - 2x); 2 - 2x are equivalent.

Let us take the first expression and simplify to see if we can get the second expression.

[tex] \frac{1}{2}(4 - 2x)[/tex]

Let us expand using the distributive property to get:

[tex] \frac{1}{2} (4 - 2x) = \frac{1}{2} \times 4 - \frac{1}{2} \times 2x[/tex]

This simplifies to:

[tex]\frac{1}{2} (4 - 2x) = 2 - x[/tex]

Therefore 1/2(4 - 2x); and 2 - 2x are not equivalent

APR is the price of using a credit card to borrow money. It is the annual interest rate that you will be charged if you carry a balance, and it frequently varies between credit cards.

For example, you may have one card with an APR of 9.99% and another with an APR of 14.99%.

Given:

Payments are done per month.

So, need to be converted to monthly figures.

APR per month = 27.2% /12

As, 1 year= 12

= P x (1 + 0.272/12)¹² + 96

Credit Card B deal over a year

= P x (1 + 0.303/12)¹²

Thus, the Principal for both cards to offer the same deal will be

P x (1 + 0.272/12)¹² + 96 = P x (1 + 0.303/12)¹²

Step-by-step explanation:

This is because 13 is a primary number

Final answer:

The number 1 is a factor of 13, which is a prime number with only two factors: 1 and 13 itself.

Explanation:

One number that is a factor of 13 is 1. This is because the factors of a number are integers that can be multiplied together to produce the original number. Since 13 is a prime number, its only factors are 1 and itself, 13. Factors are integers that multiply together to result in the original number. In the case of 13, the only combinations that yield 13 are 1 × 13 and 13 × 1. Since prime numbers have no other divisors besides 1 and the number itself, there are no additional factors for 13. This characteristic distinguishes prime numbers from composite numbers, emphasizing their unique role in number theory and their indivisibility by integers other than 1 and the number itself.

Involves calculating probabilities of drawing marbles from a bag. Simply put, probability is the likelihood that something will occur. When we're not sure how something will turn out, we can discuss the likelihood of different outcomes, or their probabilities. Statistics is the study of events that follow a probability distribution. This problem requires the usage of probability.

The outcomes more likely than not when drawing two marbles from the bag without replacement:

Pulling a yellow marble then a green marble (Probability calculation: (2/9) * (4/8) = 1/9)

Pulling a green marble then a yellow marble (Probability calculation: (4/9) * (2/8) = 1/9)

There are 9 tiles in total. With 'P' appearing twice, the chance of drawing 'P' (2/9) is more than 50%, making it more likely than not.

let's break it down step by step.

First, let's find out how many tiles there are for each letter:

- I: 1

- M: 1

- P: 2

- O: 1

- S: 1

- B: 1

- L: 1

- E: 1

Total number of tiles = 1 (I) + 1 (M) + 2 (P) + 1 (O) + 1 (S) + 1 (B) + 1 (L) + 1 (E) = 9 tiles

Now, let's find out the probability of each letter being drawn:

- Probability of drawing I: 1/9

- Probability of drawing M: 1/9

- Probability of drawing P: 2/9

- Probability of drawing O: 1/9

- Probability of drawing S: 1/9

- Probability of drawing B: 1/9

- Probability of drawing L: 1/9

- Probability of drawing E: 1/9

Now, let's calculate the probability of drawing a letter that appears more than once.

In this case, the letter 'P' appears twice. So, the probability of drawing a 'P' is 2/9.

Now, let's determine which outcomes are more likely than not.

The probability of an event being more likely than not is greater than 50%.

From our calculations, the probability of drawing 'P' (2/9) is greater than 50%, making it more likely than not to draw 'P'.

Thus, the outcome of drawing 'P' is more likely than not.

Carlos made the mistake that he did not combine like terms (3 x and 2 x) properly and did not use addition property of equality.

Step-by-step explanation:

Carlos did the work as 3 x + 2 x - 6 = 24

We need to find his mistake that he made in above given.

Here, he did not add the like terms (3 x and 2 x)

             3 x + 2 x = 5 x

Therefore, his work should be

             5 x  - 6 = 24

Also, he did not use addition property of equality. It means the equation remains same even though the same number gets added on both sides. It would be

                          5 x  - 6 = 24

                                 + 6 = + 6

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

                           5 x = 30

Dividing 30 by 5, we get answer as '6'. Hence,

                            [tex]x=\frac{30}{5}[/tex] = 6

So, stated the above two are the mistakes found in carlos work.
