ANSWER:

+ 4 7/8

STEP-BY-STEP EXPLANATION:

Assuming that we start in week 0, with a total of 0 points, we must operate the changes in each week and the value opposite to that result must be the change necessary to return to the original value.

Just like that:

Which means that to return to the initial value, 4 7/8 points must be added

To graph the inequality, we need to take the following steps:

0. Draw a number line.

1. Draw circles over -4 and 2; in this case the circles are hollow since the inequality only has exact signs.

2. Join them with a straight line.

With this in mind the graph of the inequality is:

The inequality is written in interval notation as:

4π/5 and -16π/5 are Coterminal angles with -6π/5

an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle

Coterminal angles are angles that share the same initial and terminal sides. To find an angle coterminal to another you can do so by simply adding or subtracting any multiple of 360 degrees or 2 pi radians.

The given angle is -6π/5

We need to add 2π for finding coterminal angle

-6π/5+2π

4π/5

We need to subtract 2π for finding coterminal angle

-6π/5-2π

-6π-10π/5

-16π/5

Hence 4π/5 and -16π/5 are Coterminal angles with -6π/5

Answer:

carol

Step-by-step explanation:

Beth’s hair can be represented as 1 since everyone else is a fraction of her hair  so we just convert the other 2 fractions to make them have the same denominator

4x3/5x3=12/15

2x5/3x5=10/15

10 is less than 12 so carol has the shortest hair

Hopes this helps please mark brainliest

To help visualize, let's say Beth's hair is 15 inches:

Beth = 15"

Abbey = 4/5 * 15" = 12"

Carol =  2/3 * 15" = 10"

Carol has the shortest hair.

Missing coordinates for the ordered pairs given are A= 4 and B= 18.

An integer pair used to define a point's location on a coordinate plane using the horizontal and vertical separations from the two reference axes Coordinates are two numbers (Cartesian coordinates) or, less frequently, a letter and a number that identify a specific location on a grid, also known as a coordinate plane. They are frequently represented by the x-value and y-value pair (x,y). The x (horizontal) and y (vertical) axes are the two axes of a coordinate plane with four quadrants (vertical)

The total volume of the solid shape is 756π cm³.

There is a solid shape. The shape is formed by joining a cone with a hemisphere. The radius of the hemisphere is equal to the radius of the base of the cone. The height of the cone is 10 cm. The volume of the cone is 270π cm³. We need to find the total volume of the solid shape. The total volume is the sum of the volumes of the cone and the hemisphere. Let the radius be "r". The volume of the cone is (1/3)πr²h. So, we can find the radius.

270π = (1/3)πr²h

810 = r²*10

r = √81 = 9

The volume of the hemisphere is (2/3)πr³ = (2/3)π9³ = 486π cm³. The total volume of the solid shape is V = 270π +486π = 756π cm³.

Step-by-step explanation:

y = 1/4 is the equation of a horizontal line parallel to the x- axis.

A line perpendicular to it will be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (- 6, - 9 ) with equation

x = - 6 →

Option B

Answer:

B

Step-by-step explanation:

y = [tex]\frac{1}{4}[/tex] is the equation of a horizontal line, parallel to the x- axis and passing through all points with a y- coordinate of [tex]\frac{1}{4}[/tex]

A line perpendicular to it will be a vertical line parallel to the y- axis, with equation

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (- 6, - 9 ) with x- coordinate - 6 , then

x = - 6 ← equation of perpendicular line

The graphs of the absolute value function y = 2|x + 2| - 6 and the horizontal line y = -2 are given on the image at the end of the answer.

The definition of the absolute value function is given as follows:

y = |x - h| + k.

In which the coordinates of the vertex are (h,k), representing the turning point of the graph of the absolute value function, the point in which the function makes the "V".

In this problem, the definition of the function is:

y = 2|x + 2| - 6.

Hence the coordinates of the vertex are:

(-2, -6).

The multiplication by 2 represents a vertical stretch but is not related to the vertex of the function.

y = -2 is a horizontal line, and the graph with these two functions is given by the image at the end of the answer.

The value of x in the given equation, 6x + 1.6 = 58, is x = 9.4

From the question, we are to determine the value of x in the given equation.

The given equation is

6x + 1.6 = 58

To determine the value of x in the equation, we will determine the value of the unknown variable.

The unknown variable in the given equation is x.

Thus, we will determine the value of x.

Solving the equation for x

6x + 1.6 = 58

Subtract 1.6 from both sides of the equation

6x + 1.6 - 1.6 = 58 - 1.6

6x = 56.4

Divide both sides of the equation by 6

6x/6 = 56.4/6

x = 9.4

Hence, the equation solved for x gives x = 9.4

The exponential form of  1/6 × 1/ 8 = 1/32 = 3.125 × [tex]10^{-5}[/tex]

The given numbers are 1/6 and 1/8

and exponential form means that we would have to write these numbers in such a way that the number can be expressed in the form 10 raised to the power of an integer.

When we solve 1/6

we will get 1/6 = 0.166

and when we solve 1/8 we will get

1/8 = 0.125

thus when we multiply 1/6 × 1/ 8 = 1/32

which when solved will give us

0.03125

1) Let's write the following system of linear equations, and then solve them by the elimination method.

The first thing to do is to proceed with the elimination of one variable. In this case, let's chose to start with

x-6y+2z=5 x -2

2x-3y+z=4

3x+4y-z=-2

2x-12y+4z=10

2x-3y+z=4

3x+4y-z=-2

Adding these two equations:

2x-3y+z=4

-2x+12y-4z=-10

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

9y -3z =-6

Now getting the other equations, let's eliminate another variable, in this case, "x"

-2x+12y-4z=-10 x 3

3x+4y-z=-2 x 2

Adding them

-6x +36y -12z=-30

6x+8y-2z=-4

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

0 44y -14z=-34

2) Now that we have a simpler system of two variables "y" and " z" let's operate them. Choosing a factor that we can multiply and cancel out the y variable, in this case, let's pick the Least Common Multiple between 9 and 44 = 396, so let's multiply them by

9y -3z = -6 x 44

44y-14z=-34 x -9

396y -132z = -264

-396y+126z=-306

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

6z =-42

z=-7

Plugging into the equation 9y -3z =-6

9y-3(-7)=-6

9y +21 =-6

9y=27

y=3

And for x

x-6y+2z=5

x-6(3)+2(-7)=5

x+18-14=5

x+4=5

x=1

3) So the solution for that system is (1, 3, -7).
