Answer:

[tex]4x^2 - 9x - 5 = 0[/tex]

Step-by-step explanation:

To place the equation in standard form, we expand the operations. So

[tex]4(x-1)^2 = x + 9[/tex]

[tex]4(x^2-2x+1) = x + 9[/tex]

[tex]4x^2 - 8x + 4 - x - 9 = 0[/tex]

Combining the like terms:

[tex]4x^2 - 9x - 5 = 0[/tex]

The required figure has been attached below could be the result of dilating a given triangle with a scale factor greater than 1. The correct answer would be an option (C).

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

The triangle has points (0, 0), (0, 3), and (6, 0) which are given in the question.

As per option (C), we have

On a coordinate plane, a triangle has points (0, 0), (0, 5), and (10, 0).

This result of dilating a given triangle with a scale factor greater than 1.

The required figure has been attached below which represents the dilation.

The correct answer would be an option (C).

This question is incomplete, the complete question is;

Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score. He found the least-squares regression line to be y"  = -1.5x + 85.

He also calculated that the value of r, the correlation, was -0.61.

what is the correct value of the coefficient of determination R² and give a correct interpretation of its meaning

Answer:

Interpretation of coefficient of determination R² = 0.3721

R² = 0.3721, meaning 37.21% of the total variation in test scores can be explained by the least square regression line

Step-by-step explanation:  

Given the data in the question;

the least square regression line is;

y"  = -1.5x + 85

the correlation coefficient r = -0.61

Now, the coefficient of determination R² is square of correlation coefficient r

R² = -61²

R² = 0.3721

Answer:

6xy(x+2y)

Step-by-step explanation:

6x²y+12xy²

The GCF between 6 and 12 is 6. Factor out 6.

= 6(x²y+2xy²)

The GCF between x² and x is x. Factor out x.

= 6x(xy+2y²)

The GCF between y and y² is y. Factor out y.

= 6xy(x+2y)

Therefore, the GCF of the expression is 6xy and the factored expression is 6xy(x+2y).

Answer:

(20 + 1) + G

Step-by-step explanation:

Using the information given, it is found that:

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

Item a:

The slope is given by the change in y(total bill) divided by the change in x(number of days), hence:

[tex]m = \frac{506 - 338}{19 - 12} = 24[/tex]

The slope is of 24, which means that for each day, the total bill increases by $24.

Item b:

[tex]y = 24x + b[/tex]

[tex]338 = 24(12) + b[/tex]

[tex]b = 50[/tex]

Hence, the linear equation is: [tex]y = 24x + 50[/tex]

Answer:

Nathan must order 21 sets of forks for the restaurant.

Step-by-step explanation:

Since Nathan needs to order some new supplies for the restaurant where he works, and the restaurant needs at least 571 forks since there are currently 361 forks, if each set on sale contains 10 forks, to determine the number of sets to buy you must perform the following calculation:

(571 - 361) / 10 = X

210/10 = X

21 = X

So Nathan must order 21 sets of forks for the restaurant.

300.75 you need to find the length, width, and height. then multiple everything together and then by 2

Answer:

280 in^3

Step-by-step explanation:

Basically, volume is length*width*height (length*width = base area)

So, you just multiple 10, 4, and 7 together. 4 * 7 = 28, and 28 * 10 is 280. Don't forget to make the units cubed (in^3)!

Answer/Step-by-step explanation:

✔️(3x² - 7x + 14) + (5x² + 4x - 6)

3x² - 7x + 14 + 5x² + 4x - 6 (distributive property)

Add like terms

3x² + 5x² - 7x + 4x + 14 - 6

8x² - 3x + 8

Therefore:

✅(3x² - 7x + 14) + (5x² + 4x - 6) is equivalent to expression 8x² - 3x + 8.

✔️(2x² - 5x - 3) + (-10x² + 2x + 7)

2x² - 5x - 3 - 10x² + 2x + 7 (distributive property)

Add like terms

2x² - 10x² - 5x + 2x - 3 + 7

-8x² - 3x + 4

Therefore:

✅(2x² - 5x - 3) + (-10x² + 2x + 7) is equivalent expression to -8x² - 3x + 4

✔️(12x² - 2x - 13) + (-4x² + 5x + 9)

12x² - 2x - 13 - 4x² + 5x + 9

12x² - 4x² - 2x + 5x - 13 + 9

8x² + 3x - 4

Therefore:

✅(12x² - 2x - 13) + (-4x² + 5x + 9) is equivalent expression to 8x² + 3x - 4
