Is the relation a function (14,15),(5,7),(3,10),(11,1),(5,8)

Answers

A set of ordered pairs is called a $\textit{relation}$ :

{(14,15),(5,7),(3,10),(11,1),(5,8)} is a relation.

The pairs are called "ordered" because the order is important, for example:
(3, 4) and (4, 3) are 2 different things. In the first pair 3 is the $\textit{first coordinate}$ , but in the second one 3 is $\textit{second coordinate}$

A relation is a $\textit{function}$ if no 2 first coordinates of the points are equal.

In the given relation, the first coordinates of points (5,7) and (5,8) are equal, so the relation is not a function.

Find a pair of irational numbers whose sum is irational

Answers

Answer:

√2 and √3

Good Luck!!!

Final answer:

A pair of irrational numbers whose sum is irrational does not practically exist. The sum of two irrational numbers can be either rational or irrational, and this solely depends on the numbers being added together.

Explanation:

The irrational numbers can be defined as any real number that is not a rational number. However, the sum of two irrational numbers is not always irrational. It could be rational or irrational depending on the numbers you're adding. However, you've asked for a case where the sum is also irrational. Let's consider two irrational numbers √2 and -√2. √2 is irrational. Likewise, -√2 is also irrational. However, when added (√2 - √2), they result in 0 which is not irrational. Therefore, it's near impossible to find two irrational numbers whose sum is also irrational.

: Resolver el sistema de ecuaciones por el método de reducción. -x + 3y = 6 x + y = 2

Answers

Answer:

$x=0\ny=2$

Step-by-step explanation:

El método de reducción también llamado Suma y Resta, consiste en multiplicar una o ambas ecuaciones de tal manera que los coeficientes de una de las incógnitas sean iguales y de signo contrario, de tal forma que se eliminen al sumar las ecuaciones.

Nuestras ecuaciones son:

$-x+3y=6\nx+y=2$

En este caso podemos observar que x y -x son iguales y de signo contrario así que no tendremos que multiplicar y podemos sumar ambas ecuaciones.

Al sumarlas tenemos que:

$4y=8\ny=2$

Ahora sustituímos el valor que encontramos de y en la segunda ecuación para poder obtener el valor de x.

$x+y=2\nx+2=2\nx=2-2\nx=0$

Por lo tanto, x = 0 y y = 2

Answer:

x = 5

Step-by-step explanation:

Because the red-marked lines are parallel, we know that the ratios are the same

5x : 45 = 20 : 36

5x/45 = 20/36

5x * 36 = 20 * 45

5x * 4 = 20 * 5

5x * 1 = 5 * 5

x = 5

The value of function h (-5) will be;

⇒ h (-5) = 10

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The function is,

⇒ h (x) = - 4x - 10

Now,

Here, The function is,

⇒ h (x) = - 4x - 10

So, To find the value of h (-5) as;

Substitute x = - 5 in above equation as;

⇒ h (x) = - 4x - 10

⇒ h (-5) = - 4 × -5 - 10

⇒ h (-5) = 20 - 10

⇒ h (-5) = 10

Thus, The value of function h (-5) will be;

⇒ h (-5) = 10

Answers

x=number of corect
y=number of incorrect
5 points for each correct so 5x
-1 point for each incorrect so -y

5x-y=76
solve for x and y

I like putting it into slope intercep tofrm which is y=mx+b
add y to both sides
5x=76+y
subtract 76 from both sides
5x-75=y
y=5x-76

subsitute values for x and get values for y
remember, that julia cannot answer a negative number of incorrect questions so y must be greater than or equal to 0

so solve for minimum
0<5x-76
add 76 to both sides
76<5x
divide by 5
15.2<x
you cannot answer a fraction of a correct quesiton so round up
16 is the minumum number of queswtions correctlyh answered

so
x>16

subsitute 16 for x
y=5(16)-76
y=80-76
y=4

as we subsitute more numbers over 16, we get these points
so (x,y)
(16,4)
(17,9)
(18,14)
(19,19)
(20,24)
(21,29)
(22,34)
(23,39)
x=correct answer
y=wrong answers
