Step-by-step explanation:

1/2 times 4 is 2 and 2 minus 2 is 0

Answer:

y=0

Step-by-step explanation:

Substitute x in place of x

y=[tex](\frac{1}{2} *4)-2[/tex]

y=2-2

y=0

All the possible answers are:

[tex]\frac{4}{7}[/tex], 57.14285714%

Answer:

option A : 7x - 1

Step-by-step explanation:

Area of the shaded region = [ Area of bigger rectangle] - [Area of smaller rectangle ]

Therefore, Area of bigger rectangle = length * breadth = (x - 1)(x + 5)

Therefore, Area of smaller rectangle = length * breadth = (x + 1)(x - 4)

Area of shaded region = [(x - 1)(x + 5)] - [(x + 1) ( x - 4)

= [x(x + 5) - 1(x + 5)] - [x(x - 4) + 1( x - 4)]

= [ x^2 + 5x - 1x -5] - [ x^2 - 4x + 1x - 4]

= x^2 + 5x - 1x - 5 - x^2 + 4x - 1x + 4 ....(after removing the brackets)

= x^2 - x^2 + 5x + 4x - 1x - 1x - 5 + 4.....( as (+ x^2 )and (- x^2 )get eliminated due to opposite signs)

= 9x - 2x - 1

= 7x - 1

So, option A: 7x - 1 is the correct answer.

Answers:

It's not clear which version of WX your teacher wants, so I provided both of them.

============================================================

Explanation:

Focus on the perimeters. The jump from 36 to 30 means the linear scale factor is 30/36 = 5/6

This means,

WX/YZ = 5/6

WX/5 = 5/6

6WX = 5*5

6WX = 25

WX = 25/6 which is exact

WX = 4.167 approximately

---------------

The linear scale factor is 5/6, so the area scale factor is (5/6)^2 = 25/36.

The area of figure 1 is 216 cm^2, making the area of figure 2 to be 216*(25/36) = 150 cm^2

Answer:

The answer is  

a.

$75,000

Step-by-step explanation:

The face value of the 10-year term insurance policy on a 24-year-old male is $359.25 is given as follows: $75,000.

The face value of the insurance policy is given by the equation presented as follows:

Face value = 1,000 x (Annual premium / Amount paid per $1,000 coverage )

The parameters for this problem are given as:

Annual premium = $359.25, as given in the problem.

Also, Amount paid per $1,000 coverage for 24 year old male for 10 year policy = 4.79,

Hence the face value is calculated as:

Face value = 1000 x 359.25/4.79

Face value = $75,000.

Answer:

188.53 m²

Step-by-step explanation:

Total area of the stage = area of the rectangle + area of the semicircle

Area of rectangle = Length * Width

Length = 16 m

Width = 5.5 m

Area of rectangle = 16*5.5 = 88 m²

Area of semicircle = ½(πr²)

r = ½(16) = 8 m

Area = ½(π*8²)

Area = 100.53 m²

Total area of the stage = 88 + 100.53 = 188.53 m²

Answer: C

Step-by-step explanation:

Given

Nancy bought the bag with 1100 beads to make necklaces

She found another bag with 700 beads

So, the total number of beads is the sum of two i.e. 1800 beads

It takes 50 beads per necklace

The number of necklaces that can be formed is

[tex]\Rightarrow \dfrac{1800}{50}\\\\\Rightarrow 36\ \text{Necklaces}[/tex]

I used a graphing program to graph the given system. I also graphed the points given.

Options B's choice lies in the double shaded area, so it would be a solution to the system.

See the graph attached!

Hope this helps you!  

Answer:

5 1/10 c or 3 1/10 +2

When you simplify the expression, you combine like terms. 5 7/10 c and -2 3/5 c are like terms. You multiply two on the numerator and denominator to make it 6/10. You subtract 2 6/10c from 5 7/10c to make it 3 1/10. This next step is easy. 8 and -6 are like terms. So you subtract 6 from 8 to get two. The final step is optional. 3 1/10 + 2= 5 1/10

Answer:

[tex]\sqrt{40}[/tex] or 6.32

Step-by-step explanation:

We can find the distance between two points by using this formula

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where the x and y values are derived from the given points

The points given are ( -2 , 5 ) and ( 4 , 3 )

So we plug in the x and y values of those coordinates into the distance formula

[tex]\sqrt{(4-(-2)^2+(3-5)^2} \\4-(-2)=6\\3-5=-2\\d=\sqrt{6^2+-2^2} \\6^2=36\\-2^2=4\\36+4=40\\d=\sqrt{40}[/tex]

or 6.32

Answer:

A. 2.2

Step-by-step explanation:

edge 21-22

Answer:

El precio de cada falda es 25.

El precio de cada blusa es 40.

Step-by-step explanation:

Un sistema de ecuaciones es un conjunto de ecuaciones con las mismas incógnitas. Un  sistema de ecuaciones lineales es un sistema de ecuaciones en el que cada ecuación es lineal.

Entonces, un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Una solución de un sistema es una asignación de valores para las incógnitas que hace  verdadera cada una de las ecuaciones. Es decir, resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

En este caso, se debe plantear un sistema de ecuaciones, donde las variables son:

Carmen compro 5 blusas y 4 faldas por 300. Esto se plantea mediante la expresión:

5*x + 4*y= 300

Gaby adquirió 2 blusas y 6 faldas por 230, expresado mediante la expresión:

2*x + 6*y=230

Entonces el sistema de ecuaciones a resolver es:

[tex]\left \{ {{5*x+4*y=300} \atop {2*x+6*y=230}} \right.[/tex]

En el método de sustitución se comienza con una ecuación en el sistema y se despeja una  incógnita en términos de la otra incógnita. En este caso, despejando x de la primer ecuación se obtiene:

5*x= 300 - 4*y

[tex]x=\frac{300 - 4*y}{5}[/tex]

A continuación se sustituye la expresión hallada en la otra ecuación, para  obtener una ecuación con una incógnita y, a continuación se despeja esa incógnita. Entonces:

[tex]2*\frac{300 - 4*y}{5} + 6*y= 230[/tex]

[tex]\frac{2}{5}*(300 - 4*y) + 6*y= 230[/tex]

[tex]\frac{2}{5}*300 - \frac{2}{5}*4*y + 6*y= 230[/tex]

[tex]120 - \frac{8}{5}*y + 6*y= 230[/tex]

[tex]- \frac{8}{5}*y + 6*y= 230-120[/tex]

[tex]\frac{22}{5}*y = 110[/tex]

y= 110 ÷ [tex]\frac{22}{5}[/tex]

y= 25

Entonces, el precio de cada falda es 25.

Por último, se sustituye el valor  hallado en la expresión [tex]x=\frac{300 - 4*y}{5}[/tex] para despejar la incógnita restante:

[tex]x=\frac{300 - 4*25}{5}[/tex]

x= 40

Entonces, el precio de cada blusa es 40.

Answer:

f'(×)=(y+2)^1/5 -5
