Answer:

(-1,4)

Step-by-step explanation:

The given system of inequalities is:

x>-2:(red region)

y\le2x+7: (blue region)

The graph of the system f inequalities is shown in the attachment.

The points that lies in the intersection of the red and blue region is the solution to the inequality.

From the graph (-1,4) is a solution to the system of inequalities.

Answer:

The graph in the attached figure

The point  (-1,4)  represent a solution

Step-by-step explanation:

we have

x> -2----> inequality A

y\leq 2x+7 ----> inequality B

using a graphing tool

The solution is the shaded area

see the attached figure

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution of the system of inequalities

The point  (-1,4)  represent a solution

Certain circle can be represented by the following equation.
kirill115 [55]

Answer:

Center of the circle is (-9, -7)

Radius of the circle = 5 units

Step-by-step explanation:

Given question is incomplete: here is the complete question.

Certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0.

What is the center of this circle ?

What is the radius of this circle ?

Since equation of the circle has been given by the equation,

x² + y² + 18x + 14y + 105 = 0

Now we will convert this equation to the standard form of the circle.

x² + 18x + y² + 14y = -105

[x² + 2(9)x] + [y² + 2(7)x] = -105

[x² + 2(9)x + 9²] + [y² + 2(7)y + 7²] = 9² + 7² - 105

(x + 9)² + (y + 7)² = 81 + 49 - 105

(x + 9)² + (y + 7)² = 25

(x + 9)² + (y + 7)² = 5²

By comparing this equation with the standard equation of the circle → (x - h)² + (y - k)² = r²

Center of the circle is (-9, -7) and radius of the circle is 5 units.

Haley makes earrings and packages them into cube boxes that measure 1/6 foot wide. How many 1/6 foot cubic boxes can she fit int
alexandr402 [8]

Answer:  28 cube boxes.

Step-by-step explanation:

The volume of a cube can be found with this formula:

V_{(c)}=s^3

Where "s" is the lenght of any edge of the cube.

 You need to find the volume of a cube box:

V_1=s^3=(\frac{1}{6}ft)^3=\frac{1}{216}ft^3

To find the volume of the shipping box, first we must convert the mixed number to  an improper fraction. To do it, multiply the whole number part by the denominator of the fraction and add this product to the numerator.

The denominator does not change.

Then:

1\ \frac{1}{6}=\frac{(1*6)+1}{6}=\frac{7}{6}

Knowing the dimensions of the shipping box, you can calculate its volume by multiplying its dimensions. Then, this is:

V_2=(\frac{7}{6}\ ft)(\frac{1}{3}\ ft)(\frac{1}{3}\ ft)=\frac{7}{54}\ ft^3

Finally, in order to find the  number of cube boxes can Haley fits into a shipping box, you must divide the the volume of the shipping box by the volume of one cube:

\frac{\frac{7}{54}ft^3}{\frac{1}{216}ft^3}=28
