What is the graph of a linear equation in two variables called?.

Answer:r=175 this is for IXL I hope this helps

Step-by-step explanation:

r/-25 =-7

Multiply both sides of the equation by -25

-25 times r/-25=-25 time (-7)

Multiplying two negatives equals a positive: (-) times (-) =(+)

25•r/25=-25•(-7)

then

Cancel out the greatest common factor 25

R=-25 times (-7)

Also Multiplying two negatives equals a positive: (-) times (-) =(+)

r=25 times 7

Multiply the numbers 25•7

Then you get

R=175

A mixed number is a whole number, and a proper fraction represented together.

Now, According to the question:

A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction.

A fraction denotes a portion of a whole. Therefore, if we have to read a fraction say ¾, then it read as three-fourth of a whole. In the same way, we read the other fractions such as:

½ – half of a whole

¼ – one-fourth of a whole

The correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.

In mathematics,

→The greater than symbol (>) is used to indicate that one value is larger than another. For example, if we say "A > B," this means that the value of A is greater than the value of B.

→The less than symbol (<) is the opposite, it indicates that one value is smaller than another. For example, if we say "A < B," this means that the value of A is less than the value of B.

→The greater than or equal to symbol (≥) indicate that one value is larger than or equal to another. For example, if we say "A ≥ B," this means that the value of A is greater than or equal to the value of B.

→The less than or equal to symbol (≤) indicate that one value is smaller than or equal to another. For example, if we say "A ≤ B," this means that the value of A is less than or equal to the value of B.

These symbols are commonly used in mathematical expressions, equations, and inequalities.

To write "greater than 35" in mathematical notation, you would use the greater than symbol (>) followed by the letter 35. For example:

A > 35

This means that A is greater than 35.

Therefore, the correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.

The factors of polynomial a² - 2ab + b² is equals to the (a - b)², that is (a -b) and (a-b).

To determine the factors we can use the concept of splitting the middle terms and first making the pair of two terms and then finding the common factors from the paired terms and finally the factors for the expression. We have an expression, a² - 2ab + b². Using the concept of to split the middle term. As we see there is three terms in the expression.

Thus, we can rewrite the expression as

=> a² - ab - ab + b²

Make the pair of two terms in the above expression, (a² - ab) - ( ab - b²).

Take common factors from the paired terms,

=> a(a - b) - b(a - b).

Take the common factors in the above equation => (a - b) (a - b)

=> (a - b)¹⁺¹ = (a + b)²

Hence, factor of a² - 2ab + b² is (a-b)² i.e., (a - b) and (a - b).

Yes, the distributive law is followed by the addition arithmetic operation. 

Distributive Property of Multiplication Over Addition: This implies that the operation involves dividing or distributing the things. The distributive law applies to addition and subtraction arithmetic operation.

For example, let us multiply 8 by the sum of (20 + 3). Mathematically, we can represent this as 8 (20 + 3). First, use the distributive property to multiply each addend by 8. This is called distributing the number 8 over two addenda and then adding their products. That is, multiplication of 8(20) and 8(3) will be performed first, then addition. The result is 8 (20) + 8 (3) = 160 + 24 = 184.

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².

Given here: A quadrilateral WXYZ with ∠Z=75 and ∠X=105

Let P be a point on ZW such that ZP=x and WP=4-x, then we form a right-angled triangle ΔZPY with tan 15°=x/PY

∴ PY=x/tan 15

       =3.732x

Now using Pythagoras' theorem we get ZY as

 [tex]\sqrt{13.927x^2+x^2} \\=\sqrt{14.92x^2}\\ =3.862641x[/tex]

Now let's connect the diagonal ZX we get the right triangle ZWX

Thus using Pythagoras' theorem we get

ZX=[tex]\sqrt{4^2+4^2}[/tex]

    =4√2

Again let Q be an extension such that YQ=4-x & ∠YXQ=75°

Thus Sin 75=4-x/√N

            √N=4-x/0.965923

squaring both sides we get N=(4-x)²/0.9330127........(1

Now using the Pythagoras theorem in ΔZYX we get

√N=

[tex]\sqrt{ZX^2-ZY^2} \\=\sqrt{32-14.92x^2} \\[/tex]

⇒N=32-14.92x²..,.......2)

Thus equation two values of N we get

(4-x)²/0.9330127=32-14.92x²

16-8x+x²=29.8564-13.920549x²

14.921x²-8x-13.856=0

Thus using the quadratic formula we get the value of x as

x= 8±29.85 /29.84

x=1.2684  (∵ Distance cannot be negative)

∴ Value of N=32-14.92×1.2684

                    N=13.075

                   √N=3.6159

Hence, The value of √N is 3.16159

Answer:

m = 24

Step-by-step explanation:

To solve the equation m/3-7 =1, we can start by isolating m on one side of the equation. To do this, we will add 7 to both sides of the equation:

m/3 - 7 + 7 = 1 + 7

m/3 = 8

The next step is to multiply both sides of the equation by 3 to get rid of the fraction:

m/3 * 3 = 8*3

m = 24

So the solution to the equation is m=24
