(6n-7)+(8n+2)=23 HELP FAST PLEASE

Answer:

d) x ≥0

y ≥ 0

x + y ≥ 5

29.5x + 43y ≤ 200

Step-by-step explanation:

If x and y represent the number of tickets Paige purchased for the 2 types of seats.

Paige would like to attend at least 5 concerts.

This means, Paige would like to attend 5 or more concerts

Hence, the Inequality =

x ≥0

y ≥ 0

x + y ≥ 5

Also, we are told in the question that:

There are two types of seats at the concerts, which are priced at $29.50 and $43.00. Paige would like to spend no more than $200.

This means Paige was to spend less than or equal to $200

Therefore, the Inequality equation is:

29.5x + 43y ≤ 200

Therefore, the system of inequalities could Paige use to model this situation is option D

x ≥0

y ≥ 0

x + y ≥ 5

29.5x + 43y ≤ 200

Answer:

d) x ≥0

y ≥ 0

x + y ≥ 5

29.5x + 43y ≤ 200

Answer:

7/8

First Step: 1/2 converts to 4/8

Second Step: Add 4/8 and 3/8

4/8 + 3/8 = 7/8

Answer/Step-by-step explanation:

a. Angle y is vertically opposite the angle that measures 80°. Vertically opposite angles are said to be equal to each other, therefore, y = 80°

x + y + 50° = 180° (sum of angles in a ∆)

x + 80° + 50° = 180 (substitution)

x + 130° = 180°

x = 180° - 130° (subtracting 130 from each side)

x = 50°

b. x + 50° = 120° (sum of the 2 opposite interior angles in a ∆ = the exterior angle of the ∆)

x = 120 - 50 (subtracting 50 from each side)

x = 70°

y + x + 50° = 180° (sum of angles in a ∆)

y + 70° + 50 = 180° (substitution)

y + 120° = 180°

y = 180 - 120 (subtracting 120 from each side)

y = 60°

Answer:

63 centimeters

Step-by-step explanation:

Answer: 63 cm tall.

Step-by-step explanation: Yolanda's sunflower is 12 cm more than Jean's sunflower. Yolanda's sunflower is 75cm. To find Jean's sunflower's size in cm simply subtract 12 cm from 75 cm.

75 = 12 = 63

So, Jean's sunflower is 63 centimeters tall.

Step-by-step explanation:

Let [tex]$X_1, X_2, X_3,$[/tex] . . . ,Xn be the random sample of n employee's sick days. It is given that the random samples follows the  Normal distribution along with standard deviation of 7 days. Let

[tex]X_i\sim N(\mu ,7)[/tex]

[tex]\bar{X} =\frac{1}{n}\Sigma X_i\sim N(\mu,\frac{7}{\sqrt n})[/tex]

or   [tex]Z=\frac{\bar{X}-\mu}{7 /\sqrt n} \sim N(0,1)[/tex]

So,

[tex]P(-Z_{\alpha /2} \leq Z\leq Z_{\alpha /2} ) = 1- \alpha[/tex]

[tex]P(-Z_{\alpha /2} \leq \frac{\bar{X}- \mu}{7 / \sqrt n}\leq Z_{\alpha /2} ) = 1- \alpha[/tex]

[tex]P(\bar{X}-\frac{7}{\sqrt n} Z_{\alpha / 2} \leq \mu \leq \bar{X}+\frac{7}{\sqrt n} Z_{\alpha / 2} ) = 1- \alpha[/tex]

Therefore, the confidence interval of the population mean for α = 0.05 is

= [tex]P(\bar{X}-\frac{7}{\sqrt n} Z_{\alpha / 2} , \bar{X}+\frac{7}{\sqrt n} Z_{\alpha / 2} )[/tex]

= [tex]P(21-\frac{7}{\sqrt 20} Z_{0.05 / 2} , 21+\frac{7}{\sqrt 20} Z_{0.05 / 2} )[/tex]

= (17.93, 24.07)

You're Welcome!

The graph of the coordinates is plotted and attached.

A diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.

We have the following table -

[x]         f(x)    

- 4        16

- 3        -2

- 2         0

- 1          6

0          0

1           -2

The given table represents the coordinates -

(- 4, 16) , (- 3, - 2), ( - 2, 0) , ( - 1, 6) , (0, 0) , (1, - 2)

The graph of the coordinates is plotted and attached.

Answer:

Identify the input values.

Identify the output values.

If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.

Step-by-step explanation:

Answer:

Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.

Example:

Given f(x) = x2 + 3x – 1, find

a) f(1)

b) f(–1)

c) f(a)

d) f(x – 1)

Solution:

a) f(1) = (1)2 + 3(1) – 1 = 3

b) f(–1) = (–1)2 + 3(–1) – 1 = –3

c) f(a) = a2 + 3a – 1

d) f(x – 1) = (x – 1)2 + 3(x – 1) – 1

= x2 – 2x + 1 + 3x – 3 – 1 = x2 + x –3

Answer:

Half an inch

Step-by-step explanation:

Perimeter of the frame = 28 inches

Length fo the frame = 7 + x + x = (7 + 2x) inches

Width of the frame = 5 + x + x = (5 + 2x) inches

Perimeter of a rectangle is given as: 2(length) + 2(width)

Therefore:

28 = 2(7 + 2x) + 2(5 + 2x)

Solve for x

28 = 2*7 + 2*2x + 2*5 + 2*2x

28 = 14 + 4x + 10 + 4x

Collect like terms

28 = 14 + 10 + 4x + 4x

28 = 24 + 8x

Subtract 24 from both sides

28 - 24 = 24 + 8x - 24

4 = 8x

Divide both sides by 8

4/8 = 8x/8

½ = x

Width of the frame = x = ½ of an inch

Answer:

approximately 21 years

Step-by-step explanation:

-From the problem, we are given the equation I = Prt

-We're also given three numbers

-From that, we can determine which number should be plugged into the equation:

-The only value we are not given is t as we need to solve for this value

-Now plug all these values into the equation:

It takes approximately 21 years for the investment amount to be worth $2308.

Answer:

Su diferencia es -1.2

Step-by-step explanation:

Analizando la jerarquía de los números esta va de ascendente (mayor) a decendente (menor).

Como se puede ver tu primer número es 1.1 y el que le sigue es -0.1, ahí se podría hacer la primera ecuación que es una resta de números 1.1-0.1=1.2. Vamos a retomar el segundo valor y poner el resultado que nos dio al principio (recordando la ley de los signos:negativo más negativo, pues se suman pero el signo negativo estará presente ahí), para tener sentido aquí hay una explicación.

-0.1-1.2=-1.3 y lo mismo hacemos -1.3-1.2=-2.5
