Answer:

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.

Step-by-step explanation:

It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation: a²+b²=c², where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides.

Answer:{x,y}={-1,-4}

Step-by-step explanation:

 [2]    8x = 4y + 8

 [2]    x = y/2 + 1

// Plug this in for variable  x  in equation [1]

  [1]    10•(y /2+1) - 9y = 26

  [1]     - 4y = 16

// Solve equation [1] for the variable  y

  [1]    4y = - 16

  [1]    y = - 4

// By now we know this much :

   x = y/2+1

   y = -4

// Use the  y  value to solve for  x

   x = (/2)(-4)+1 = -1

Answer:

x = 96 + (88h + 0,45p) - 25

Step-by-step explanation:

Expression that represents the total cost when Shandar keeps the truck for h days and travels a total of p mile x= 71+ 88h +0.45p

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in math when you do not know the exact number in a calculation.

Let us consider 'h' the number of additional days

let p be number of miles she drives.

let x be the total cost

Now,

For h days fare will be = 88h

For p miles fare will be = 0.45p

Coupon= $25

Total cost = Charges for first day + fare of additional h days +  charges of total p miles- coupon

x = 96 + (88h + 0,45p) - 25

x= 71+ 88h +0.45p

Hence, required equation is x= 71+ 88h +0.45p

Step-by-step explanation:

(4x-5y)-(x-y)        if x=6 and y=-4

step one:

4x=24

5y=-20

24- (-20)= 44

x-y=10

44-10=34

I'm pretty sure I'm right because I worked it out on a calculator and if it changed the minus in 4x-5y to a + then that means the minus here

(4x-5y   - < --  (x-y) is not supposed to become a + sign

The width of the pen must not be less than 45 feet

The formula for calculating the perimeter of a rectangle is expressed as:

P = 2(l + w)

Given the following

P = 190feet

l = 50feet

Required width

190 = 2(50 + w)

95 = 50 + w

w = 45

Hence the width of the pen must not be less than 45 feet

so let's take a peek at the table, so hmmm when x = -1, b(x) = 1, so we have the point (-1 , 1), and when x = 2, b(x) = 7, so we have the second point of (2 , 7)

[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{7}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{7}-\stackrel{y1}{1}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{(-1)}}}\implies \cfrac{6}{2+1}\implies \cfrac{6}{3}\implies 2[/tex]

Answer:

b

Step-by-step explanation:

Option B is correct,  A positive difference means that the students score decreased after the program, and a negative difference means that the students score increased after the program.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given that a school is implementing an SAT preparation program.

To study the program's effectiveness the school looks at participants SAT scores before starting the program and after completing the program .

The results are shown in the table.

We need to find the values in the Difference row of the table be interpreted

if we observe the table before value is less and after value is larger, and when we find the difference we get negative value.

A positive difference means that the students score decreased after the program

Negative difference means that the students score increased after the program.

Hence, Option B is correct,  A positive difference means that the students score decreased after the program, and a negative difference means that the students score increased after the program.
