Answer:

[(2*8) + 3] *4 = 76

[2*(8 - 3)]*4 = 40

Step-by-step explanation:

Los paréntesis ( ), corchetes [ ] y llaves {} son símbolos de agrupación que indican el orden de las cuatro operaciones aritméticas básicas (suma, resta, multiplicación y división). Las reglas del orden de operaciones establece que se debe realizar primero el cálculo dentro de los símbolos de agrupación.

En otras palabras, la jerarquía de operaciones es el orden en el que hay que realizar las distintas operaciones, ya que unas tienen prioridad frente a otras. Y establece primero debes empezar por resolver los paréntesis, luego los corchetes y finalmente las llaves. Es decir, cuando haya símbolos de agrupación dentro de símbolos de agrupación, calcula de adentro hacia afuera. Esto es, empieza simplificando los símbolos de agrupación en el centro.

Para obtener 76, se pueden realizar la siguiente operación combinada:

[(2*8) + 3] *4

Aplicando lo anteriormente mencionado de la jerarquía de operaciones, comienzas por resolver el paréntesis:

[16 + 3]*4

Ahora, resolviendo el corchete:

19*4

Finalmente, resolviendo la multiplicación:

19*4= 76

Entonces [(2*8) + 3] *4 =76

Para obtener 40, se pueden realizar la siguiente operación combinada:

[2*(8 - 3)]*4

Comenzando a resolver el paréntesis:

[2*5]*4

Ahora, resolviendo el corchete:

10*4

Finalmente, resolviendo la multiplicación:

10*4= 40

Entonces [2*(8 - 3)]*4 = 40

Answer:

Average rate of change =250

Step-by-step explanation:

Formula to determine average rate of change of the function,

Average rate of change = [tex]\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

Where [tex]x_1[/tex] and [tex]x_2[/tex] are the points representing number of years after year 2000.

Since [tex]x_1[/tex] = 5 and [tex]x_2=19[/tex],

[tex]f(x_2)=650[/tex]

And [tex]f(x_1)=300[/tex]

Now average rate of change = [tex]\frac{650-300}{19-5}[/tex]

                                                = [tex]\frac{350}{14}[/tex]

                                                = 250

Therefore, average rate of change of the number of influenza cases from 2005 to 2019 is 250.

Answer:

x=0.2, y=6

Step-by-step explanation:

Since y=20x+2, 5x+y=7 => 5x + (20x +2 ) = 7

                                                     25x + 2 = 7

                                                           25x = 5

                                                                x = 0.2

so y = 20x + 2 = 20* 0.2 +2 = 4 + 2 = 6

so the final solution is [tex]\left \{ {{y=6} \atop {x=0.2}} \right.[/tex]

The values of x and y for the given simultaneous equation are;

x = 0.2 and y = 6

We are given 2 simultaneous equations;

5x + y = 7   ---(eq 1)

20x + 2 = y   ----(eq 2)

Put 20x + 2 for y in eq 1;

5x + 20x + 2 = 7

25x + 2 = 7

25x = 7 - 2

25x = 5

x = 5/25

x = 0.2

Put 0.2 for x in eq 2 to get;

20(0.2) + 2 = y

4 + 2 = y

y = 6

In conclusion, the values of x and y are x = 0.2 and y = 6.

We need to use the place values to compare different numbers.

By only looking at the place value, we can see that the largest number is: 0.1

Let's see how to get the solution.

We can define place value as the place where a digit is with respect to the decimal point.

The digits that are at the far left are the larger ones, for example in:

11

The left one represents 10, while the right one represents 1:

10 + 1 = 11

The same happens when we look at the right of the decimal point, there the digits at the left will be larger than the ones at the right.

0.10 is larger than 0.01

From this, we can see that for the set:

{0.1, 0.02, 0.003, 0.0004, 0.00005}

The largest number will be the one with the leftmost first digit different than zero, which is the first one: 0.1

Given:

A rectangle has a length 5 meters more than five times the  width.

The area of the rectangle is less than 100 meters  squared.

To find:

The expression or inequality that represents all possible  widths of the rectangle.

Solution:

Let x be the width of the rectangle.

Length of the rectangle is 5 meters more than five times the  width.

[tex]length=5x+5[/tex]

Area of rectangle is

[tex]Area=length \times width[/tex]

[tex]Area=(5x+5) \times x[/tex]

[tex]Area=5x^2+5x[/tex]

The area of the rectangle is less than 100 meters  squared.

[tex]5x^2+5x<100[/tex]

[tex]5x^2+5x-100<0[/tex]

Divide both sides by 5.

[tex]x^2+x-20<0[/tex]

[tex]x^2+5x-4x-20<0[/tex]

[tex]x(x+5)-4(x+5)<0[/tex]

[tex](x+5)(x-4)<0[/tex]

It is true if one factor is negative and other is positive. So,

[tex]x-4<0\Rightarrow x<4[/tex]     ...(i)

[tex]x+5>0\Rightarrow x>-5[/tex]       ...(ii)

Using (i) and (ii), we get

[tex]-5<x<4[/tex]

Therefore, the required expression or inequality for possible

widths of the rectangle is [tex]-5<x<4[/tex].

Answer:

(-2,0)

Step-by-step explanation:

remember the rule for 90 degree clockwise is (-y,x) opposite y and x

the negative in there DOES NOT mean it will always be negative it means opposite but in this case yes it's negative because the opposite of positive is negative

The image of point (0,2) after a rotation of 90° counterclockwise about the origin is (-2, 0).

The given coordinate point is (0, 2).

Here are the rotation rules: 90° clockwise rotation: (x, y) becomes (y, -x) 90° counterclockwise rotation: (x, y) becomes (-y, x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).

The rule of 90° counterclockwise rotation: (x, y) becomes (-y, x), here

(-2, 0)

Therefore, the image of point (0,2) after a rotation of 90° counterclockwise about the origin is (-2, 0).
