(P.S., pls mark me brainliest, and have a nice day)

Answer:

x = -1

y = 2

Step-by-step explanation:

x + y = 1

y = -x + 1

y = -x + 1  (Multiply this by -1)

y = 3x +5

-y = x - 1

y = 3x +5

0 = 4x + 4

4x = -4

x = -1

x + y = 1

-1 + y = 1

y = 2

Answer:

105

Step-by-step explanation:

x + 25 + 80 = 180

x + 105 = 180

x = 75

x + y = 180

75 + y = 180

y = 105

Answer:

5 miles

Step-by-step explanation:

It is a right triangle, with 3 miles down, and 4 miles to the right

the shortest distance would be and southeast line.

Using the Pythagorean theorem, you get:

3^2 + 4^2 = x^2

9 + 16 = x^2

25 = x^2

x = 5

Answer:

i think its 2/1

Step-by-step explanation:

take those 2 points and do y2-y1

                                            -----------

                                              x2-x1

Answer:

125 and 55

Step-by-step explanation:

The total angle degree of (2x+3) and (x-6) is 180. So, you add both, and set the equation equal to 180 degrees.

2x+3+x-6=180

3x-3=180

3(x-1)=180

x-1=60

x=61

Substitute that for your angles, and you get your answers.

Answer:

A) x > 7

Step-by-step explanation:

Since it's more than, the inequality would be >

Since it's >, that means it's an open circle

So,

x > 7

y=28

so

28-26=2

Answer:

I think NOT

Step-by-step explanation:

Complete question :

Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.

Book Mean Median Mean Absolute Deviation

Art 68.7 50 15.4

Science 54.2 55 7.9

She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference?

Yes, because the mean is larger in the art book

No, because the mean is larger in the art book

Yes, because there is a lot of variability in the art book data

No, because there is a lot of variability in the art book data

Answer:

No, because there is a lot of variability in the art book data

Step-by-step explanation:

Given the data:

Book Mean Median Mean Absolute Deviation

Art __68.7 ___50 ________15.4

Science 54.2 _55 ________7.9

To make our conclusion based on data; Even though te mean number of words in the art book is greater than that of the science book, we may not be able to conclude that the mean number of words on each page of the art book is greater because the mean absolute deviation value which is a measure of the variability of the data is clearly greater for the art book than the science book. With this, we cannot make a valid inference that mean number of words on each page of the art book is greater than the science book.

Answer:

The correct answer would be obtuse

Step-by-step explanation:

An obtuse angle is an angle that has a measure of more than 90°

So if a triangle has an angle greater than 90° it would be classified as an obtuse triangle

Answer:

[tex]x=\pm1[/tex]

Step-by-step explanation:

[tex]\mathrm{log}_8(2)+\mathrm{log}_84x^2=1\\\mathrm{log}_8(2\cdot4x^2)=\mathrm{log}_8(8)\\8x^2=8\\x^2=1\\x=\pm1[/tex]

AND -1

Alternatively, you can realize that log_8(2) = 1/3 and solved that way.

Answer:

71°

Step-by-step explanation:

Kaia's window is in the shape of a trapezoid. Three of the angles are 80°, 100°, and 109°. What is the measure of the fourth angle?

The sum of angles in a trapezoid is equal to = 360°

We are given 3 angles in the trapezoid as: 80°, 100°, and 109°.

The measure of the fourth angle is calculated as:

360° = 80°+ 100° +109° + fourth angle

360° - (80°+ 100° +109°)

360° - 289°

= 71°

The measure of the fourth angle is 71°

Answer:

10ft

Step-by-step explanation:

volume= 502 ft³

or, πr²h= 502ft³

or, h= 502/(π×4²)

or, h= 9.98~10

Answer: 7

Step-by-step explanation:

\frac{-14}{-2}

Both 14 and 2 are divisible by 2, so we can divide both of these numbers by 2.

\frac{-7}{-1}

Both numbers are negative, so we can divide both of these numbers by -1.

\frac{7}{1}

This gives us 7.

Answer:

Step-by-step explanation:

=14 / -2 = 7

-14 / -2 = 14/2 = 7

Answer:

[tex]y^2-\frac{7}{2}y+3[/tex]

Step-by-step explanation:

Given polynomial is,

6y² - 7y - 2

Fro the zeros of the given polynomial,

6y² - 7y - 2 = 0

6y² - 4y - 3y - 2 = 0

2y(3y - 2) - 1(3y - 2) = 0

(2y - 1)(3y - 2) = 0

(2y - 1) = 0

y = [tex]\frac{1}{2}[/tex]

(3y - 2) = 0

y = [tex]\frac{2}{3}[/tex]

Therefore, zeros of this polynomial are m = [tex]\frac{1}{2}[/tex] and n = [tex]\frac{2}{3}[/tex]

If a polynomial has zeros as [tex]\frac{1}{m}[/tex] and [tex]\frac{1}{n}[/tex] then the zeros will be [tex]\frac{3}{2}[/tex] and 2.

Polynomial will be,

[tex](y-\frac{3}{2})(y-2)[/tex]

= [tex]y(y-2)-\frac{3}{2}(y-2)[/tex]

= [tex]y^2-2y-\frac{3}{2}y+3[/tex]

= [tex]y^2-\frac{7}{2}y+3[/tex]

Answer:

D. –x^4 + 6x^3 + 7x^2 – 4x – 4

Step-by-step explanation:

When writing in standard form you have to put the monomials from greatest to least according to their exponent.

[tex]-x^4+6x^3+7x^2-4x-4[/tex]

The first number is [tex]-x^4[/tex] because 4 is the greatest exponent we see, then comes [tex]+6x^3[/tex] which is next because it has the second greatest exponent. And so on and so on.
