8.Convert the line into slope intercept form: 3x + 5y =-15

Answer:

19x^7y^16

Step-by-step explanation:

And usually means to add, so combine your like terms:

12x^5y^7 + 7x^2y^9

12 + 7 = 19

x^5 + x^2 = x^7

y^7 + y^9 = y^16

Answer:

Step-by-step explanation:

(12x⁵ y⁷) * (7x²y⁹) = (12*7) * (x⁽⁵⁺²⁾ ) (y⁽⁷⁺⁹⁾)

                            = 84x⁷y¹⁶

In exponents multiplication, if base are same, then add the powers.

xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾

Explanation:

When we add matrices, we must first make sure they are the same dimensions. In this case, both are 2x3 matrices, so we can add them.

To add matrices, you add the corresponding components.

For example, in the first row, first column, we have B+A = -2+4 = 2. So the value 2 will go in the first row, first column, of the answer matrix.

The other elements are handled in a similar fashion.

Answer:

|-12.5| is greater than |11.5|

Step-by-step explanation:

because the brackets thingys will remove the neagtive sign so it would just be 12.5 And 12.5 is greater than 11.5 right?

Answer:

  (-4√494)/13i +(6√494)/13k ≈ -6.8388i +0j +10.2585k

Step-by-step explanation:

To answer this question, you need to know two things:

  1) the direction of vector v

  2) the magnitude of vector u

__

direction of v

A direction is specified by a "unit vector", one with the proper ratio of components, and a magnitude of 1. It is found from a given vector by dividing that vector by its magnitude.

The unit vector in the v direction is ...

  v/|v| = (-2i +3k)/(√((-2)² +3²) = (-2i +3k)/√13

__

magnitude of u

The magnitude of vector u is ...

  |u| = √(5² +(-2)² +3²) = √38

__

Then the desired vector is ...

  (2|u|)(v/|v|) = 2√38(-2i+3k)/√13 = (-4√494)/13i +(6√494)/13k

_____

Additional comment

We have chosen to "rationalize the denominator" by writing √(38/13) as (√494)/13.

Step-by-step explanation:

So, we have the following parameters or information from the question above:

=> that the regression equation is Score = 31.55 + 10.90 Years.

So, the regression equation is in the form of mx + c.

Thus, the coefficient that is constant = 31.55 and the coefficient that shows or represents the years = 10.90.

=> Also, we have the value which is most important in this question that is the coefficient of Determination which is represented as R-sq and has the value of 83%.

The percentage of the total variation in test scores is NOT explained by the linear relationship between years of study and test scores = 100% - 83% = 17%.

For the percentage of the total variation in test scores is explained by the linear relationship between years of study and test scores = R- sq = 83%.

Answer:

So, I know that we will have to find the Area of the "Shape" And I see a *Unlabeled/Unknown* Shape that we have to find the answer of/to.

Step-by-step explanation:

To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet. Volume is also how loud a sound is.

To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

A) [tex]0.75, \frac{3}{5}[/tex]

Step-by-step explanation:

75% can be written in fraction and decimal form.

75% = [tex]\frac{75}{100}[/tex] = [tex]\frac{3}{4}[/tex] (in its simplest form)

75% = [tex]75\div100=0.75[/tex]

∴75% is equivalent to [tex]\frac{3}{4}[/tex] and [tex]0.75[/tex], and Option A is correct.

Answer:

2.5 cm of snow fall on average each hour.

What is average?

The average formula is also known as the arithmetic mean, which is the ratio of the sum of all given observations to the total number of observations. Thus, using the average formula, the arithmetic mean for any sample of data can be calculated.

The average formula for a given set of data or observations can be expressed as:

Average Formula:

Average = (Sum of Observations) ÷ (Total Numbers of Observations)

Given:

The number of millimeters that fell throughout the course of the period divided by the number of hours is the mean hourly snowfall.

At 5:00 PM,

There are 4 hours from 6 PM to 9 PM.

So, there is 2 millimeters of snowfall as of 5 p.m.

and, 12 millimeters of snowfall as of 9 p.m.

Then, the accumulation of snow rises by

=12-2

= 10 cm in those four hours.

Thus, on an average the snow fall at rate

= 10/4

= 2.5

Hence, 2.5 cm of snow fall on average each hour.

Answer:

N = 13

Step-by-step explanation:

Move all terms containing n to the left, all other terms to the right.

Add '-3n' to each side of the equation.

24 + -3n = -15 + 3n + -3n

Combine like terms: 3n + -3n = 0

24 + -3n = -15 + 0

24 + -3n = -15

Add '-24' to each side of the equation.

24 + -24 + -3n = -15 + -24

Combine like terms: 24 + -24 = 0

0 + -3n = -15 + -24

-3n = -15 + -24

Combine like terms: -15 + -24 = -39

-3n = -39

Divide each side by '-3'.

n = 13

Simplifying

n = 13

2/6 or 1/3 simplified

Step-by-step explanation:

First multiply the numerators which is the top number of both fractions, which for this equation is 1 and 2 so 1x2=2. So your final fraction would have a numerator of 2 unless simplified. Next, multiply the denominators which are the  bottom numbers of the fraction for this one its 2 and 3 so 2x3=6. Your final fraction is 2/6, if simplified 1/3.
