Write an equation of the line that passes through (6, 1) and is perpendicular to x +2y-12=0.

Answer:

11

Step-by-step explanation:

You can plug it inot a calculator, or can make a factor tree, in which the 2 factors would be 11, so 11^2=121 and [tex]\sqrt121[/tex]=11

Answer:

11

Step-by-step explanation:

its something you basically have to just memorize and know... i dont know how to explain it, but like basically not all numbers have an even number square root. to have an even number for a square root, the number has to be able to be divided by the same 2 numbers. like 121, for it to have a whole number square root, it has to be able to be divided by 2 same numbers. or doubles... 11 times 11

11 squared is 121

square root of 121 is 11

Answer:

h = 209

Step-by-step explanation:

So we want to solve h, therefore, we must get it by itself on one side. We can do that by somehow removing the three that is with h. So how could we do that? Well, by multiplying h/3 by 3, we get h because the threes cancel out. However, whatever we do to one side, we must do it to the other too because then the equation does not hold true. So, 3 x (69 + 2/3) = 209

Answer:

49 degrees

Step-by-step explanation:

Answer:

m<E = 49°

Step-by-step explanation:

Using the straight angle theorem, we can add the angles measuring 63, 68, and the angle above the 68(let's call it x) add to 180. We can write an equation:

63 + 68 + x = 180

This means:

x = 49

Angle x is alternate interior to angle E, meaning the two are congruent and have the same measure. This means m<E = 49

Answer:

-99%

Step-by-step explanation:

Since it is going down, it'll be negative.

8,000 - 80 = 7,920

7,920 / 8,000 = 0.99

0.99 x 100 = 99%

-99%

(they might be asking for just 99% though too!)

Answer: Well I would say Jones Act, any vessel can enter Puerto Rico. In fact, many foreign vessels enter Puerto Rico regularly, importing goods from countries around the world. However, transportation of goods between two U.S. ports must be carried out by a vessel that was built in the U.S. and operated primarily by Americans.

Step-by-step explanation:

The relationship between the x and y variables in the scatter plot is

approximately linear.

(a) Increase in the y-variable follows from an increase in the x-variable

(b) The regression coefficient is approximately 0.9465

(c) The slope of the regression line is 2.5

(d) The equation of the regression line is approximately; y = 2.5·x + 10.5

(e) If x = 25, the value of y is 73

Reasons:

(a) From the attached graph, we have;

The increase in the x-variable gives a corresponding increase in the y-

variable.

(b) The correlation coefficient is given by plotting the given points using

MS Excel and finding the regression line, from which we have;

The regression coefficient is R ≈ √(0.8958) ≈ 0.9465

(c) The slope of the regression line is given by the slope of the line with

points (7, 28), and (9, 33), as follows;

[tex]Slope = \dfrac{33 - 28}{9 - 7} = 2.5[/tex]

The slope of the regression line is approximately 2.5

(d) Using the slope, m = 2.5, we get;

Equation of regression line, is y - 33 = 2.5·(x - 9)

Which gives;

y - 33 = 2.5·(x - 9) = 2.5·x - 22.5

y = 2.5·x - 22.5 + 33 =

The equation of the line is; y = 2.5·x + 10.5

(e)  If x = 25, we have;

y = 2.5 × 25 + 10.5 = 73

Therefore, if x = 25, y = 73

Answer: 4x+1 3/4=10

Step-by-step explanation: Took the test. Plus you can check to see if it equals to - 10 = 10 by replacing x with 2 1/16. Example: 4 * 2 1/16 + 1 3/4 =10. So 10 = 10 is a true match.

The given case can be represented as the equation 4x + 13/4 = 10.

A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.

Given that,

The length of board = 10 feet.

The length of piece that is cut first = 13/4 feet.

Suppose the length of each remaining piece cut into four equal parts is x feet.

Now, the expression for the total length of the board can be given as the sum of the total length of the remaining piece and the the piece that is cut first.

In mathematical form it can be written as,

4x + 13/4 = 10

Hence, the equation for the given case is 4x + 13/4 = 10.

Basically the first image goes in the first box because opposites attract and the second image is what happens when you let the magnets go. The third image would go into the second chart because same-sides repel each other and the fourth picture shows what happens if you let the magnets that have the same sides facing each other go.

Answer:

(5,0)

Step-by-step explanation:

Switch the second equation around so it matches up with the first one :

4x-6y = 20

Then solve by elimination :

-2 (2x-3y = 10) = -4x+6y = -20

-4x+3y = -20

+ 4x-6y = 20

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

-3y = 0

y = 0

Plug y as 0 into one equation :

2x-3(0) = 10

2x = 10

x = 5

Your solution would be (5,0) .

Step-by-step explanation:

To be able to compare the growth rates of these two people, we need to develop an equation to describe Ioana's growth history, just like Valentin did.

Let [tex]P_1(5, 102)[/tex] and [tex]P_2(10, 127).[/tex] Using the equation for the slope of a linear function,

[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

and this will represent the growth rate for Ioana. The slope in Valentin's equation also represents the growth rate. Using the values of the points that we picked, we get

[tex]m = \dfrac{127 - 102}{10 - 5} = \dfrac{25}{5} = 5[/tex]

The slope-intercept form of the equation that describes Ioana's growth can be written as

[tex]h_I = 5(a - 5) + b[/tex]

Note that we used (a - 5) instead of the usual variable a because the twins started recording their heights at the age of a = 5. Next, we need to figure out b, essentially Ioana's height at age 5. From the table, we can see that that b = 102. Hence, the equation for Ioana's height is

[tex]h_I = 5(a - 5) + 102[/tex]

Let's compare this with Valentin's equation for his height:

[tex]h_V = 4.5(a - 5) + 104[/tex]

We can see here that the slope for Ioana's equation is larger than Valentin's, which means that Ioana's growth rate is faster than that of Valentin, even though Valentin was taller when they first started.

Four over nine looks like 4/9 and 2 over nine looks like 2/9.
