Answer:

x < 3

Step-by-step explanation:

The standard linear equation of a <u>vertical line</u> with an undefined slope is <em>x </em>=<em> a</em>, where "a" represents the <u><em>x-intercept</em></u> of the graph.  Vertical lines have an undefined slope because it doesn't have any horizontal change.

The given graph represents the graph of a <u>vertical line</u>, whose x-intercept occurs at point (3, 0). Since the graph has a <u>dashed boundary line</u>, then it means that the linear inequality symbol used to represent the graph is "<," which implies that the endpoint, x = 3, is not included as part of the solution. Additionally, since the shaded half-plane region is towards the left-hand side of the boundary line, it means that the solution must less than 3.

Therefore, the linear equation that represents the given graph is x < 3.

Las fracciones que tienen denominador 10, 100, 1000, etc las llamamos fracciones decimales y a su vez las podemos escribir como
Sindrei [870]

Answer:

las fracciones decimales son:

21/10 = 2,1

439/100 = 4,39

34/10 = 3,4

35/1000 = 0,035

851 / 1000 = 0,851

Step-by-step explanation:

Toda fraccion cuyo denominador (el numero de abajo) es multiplo de 10 es considerada una fraccion decimal. No importa si el numerador es mayor al denominador. Justamente el sistema decimal fue concebido para facilitar la multiplicacion y division de los numeros por algun multiplo de 10.

66 randomly selected students were asked the number of pairs of shoes they have. Let X representthe number of pairs of shoes. Th
laiz [17]

Given data

1. The mean

\frac{\sum fx}{\sum f}=\frac{505}{66}=7.6515

2. The median

\begin{gathered} \text{ Median = (}\frac{\text{N+1}}{2})th \\ =(\frac{66+1}{2})th=(\frac{67}{2})th=33.5th \\ \text{The median is the 33.5th }term\text{ which is between 7 and 8} \\ \text{The median is }\frac{\text{7+8}}{2}=\frac{15}{2}=7.5 \end{gathered}

3. The sample standard deviation

\begin{gathered} SD\text{ =}\sqrt[]{\frac{\sum f|x-\bar{x}|}{\sum f}} \\ \bar{x}=7.6515 \\ SD=\sqrt[]{4.8028} \\ SD=2.1915 \end{gathered}

Solve graphically please send me by solving and clicking photo plzzzz​
Delicious77 [7]

Answer:

Subtract 5x from both sides of the equation.

7y=1−5x

x+4y=−5

Divide each term by 7 and simplify.

y=17−5x/7

x+4y=−5

Subtract x from both sides of the equation.

y=1/7−5x/7

4y=−5−x

y=1/7−5x/7

Divide each term by 4 and simplify.

y=1/7−5x/7

y=−5/4−x/4

y=1/7−5x/7

Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution. (3,−2)
