The equation of the line is x - y = 0.

The slope of the line passing through (13,-1) and (8,4).

m=y2-y1 / x2-x1

  = 4-(-1) / 8-13

  = 5 / -5

m=-1

The product of slopes is done in the case of perpendicular lines and it is 1.

The slope of another line will be

m.m1=-1

m1=-1/m

m1=-1/-1

m1=1

The equation of the line is

y-y1=m(x-x1)

y-1=1(x-1)

x-y=0.

Thus the equation of the line is x-y=0.

The polygon is a regular hexagon.

Stella is using a compass and a straight edge to construct a polygon inscribed in a circle.

Also the circle is drawn with five arc markings that lie on the circle. Also there is an additional point marked on the circle.

So there are in total 6 points on the circle. Also the lines joining these five points will be equal. So we will get a regular hexagon through this construction.

The following is the process of construction.

First she starts at a point on the circle placing the compass there. Then she will measure the radius of the circle on compass. Fixing this distance, she will draw an arc on the circle. The process is repeated by placing the compass on the new point obtained on the circle.

So in total she will get the 6 vertexes of the regular hexagon. Joining the adjacent points, a regular hexagon is inscribed inside the circle.

Per year price drop is -41.50$

The cost of an MP3 player in the year 2003 is = $ 499

The cost of an MP3 player in the year 2009 is = $ 249.99

The price drop per year will be –

We need to subtract the base year price from that of the current year price  and divide that by the difference between the base year and the current year

The year that serves as the standard against which subsequent values are measured is referred to as the base year.

The term "current year" refers to the fiscal year that has already begun but has not yet completed its cycle.

So,

The x-value of the solution of x + y = 7 , 3x - 2y = 11, is equal to 5.

The given equations are linear equations in two variables since there are two unknown variables present in these equations.

Considering equation number one to be, x + y = 7

and equation number two to be, 3x - 2y = 11

By rearranging the first equation, the value of x can be considered to be:

x + y = 7

x = 7 - y

Adding this value of x in the second equation for the solution of y;

3 (7 - y) - 2y = 11

21 - 3y - 2y = 11

Rearranging,

21 - 11 = 3y + 2y

10 = 5y

y = 10 ÷ 5

y = 2

By adding this value of y to the first equation, the value of x can be found as follows,

x + y = 7

As y = 2

x + 2 = 7

x = 7 - 2

x = 5

Hence, the value of x is calculated to be 5.

Answer:

Step-by-step explanation:

1). You would add the numbers inside of the parenthesis first this would give you (13.34) inside of the parenthesis.

2). You equation should look like 0.5(13.34)9 now then you would multiply the 0.5 to the number inside of the parenthesis and you will have (6.67)9 now.

3). Lastly you will multiply the 6.67 to the 9 and you will get 60.03 as your final answer.

a. the equation of the formula in terms of x is: x = (c - b)/a

b. x = 4 and x = 6

Where we have a, b, and c as constants of the equation, ax + b = c, and the variable is x, we can solve for the value of x as shown below:

ax + b = c

Subtract b from both sides

ax - b = c - b

ax = c - b

Divide both sides by a

ax/a = c/a - b/a

x = c/a - b/a

x = (c - b)/a

b. 3x + 7 = 19

a = 3, b = 7, and c = 19

Substitute a = 3, b = 7, and c = 19 into x = (c - b)/a

x = (19 - 7)/3

x = (12)/3

x = 4

x - 1 = 5

a = 1, b = -1, and c = 5

Substitute a = 1, b = -1, and c = 5 into x = (c - b)/a

x = (5 - (-1))/1

x = 6/1

x = 6

In summary, we have:

a. the equation of the formula in terms of x is: x = (c - b)/a

The two lines AB and XY are neither parallel nor perpendicular.

According to the question we have been given the respective coordinates which are :

 A = (-3,5)   , B = (-1,3)

X = (-4,-8)   , Y = (4,-6)

We need to find if AB and XY are parallel , perpendicular or neither.

So to find if they are parallel or perpendicular we will first find out the slope of the line. As when the slope are equal then they are parallel and if they are negative reciprocals of each other then they are perpendicular to each other .

Thus, Slope of AB =  [tex]m_{1}[/tex] =  [tex]\frac{(y_{2}-y_{1} ) }{(x_{2}-x_{1} ) }[/tex]

                                 [tex]m_{1}[/tex] = (3-5)/(-1+3)

                                 [tex]m_{1}[/tex] = -2/2

                                  [tex]m_{1}[/tex] = -1

          Slope of XY = [tex]m_{2}[/tex] = (-6+8)/(4+4)

                                       = 2/8

                                        = 1/4

As the slope of both lines are not related to each other. Hence, the lines AB and XY  are neither parallel nor perpendicular.

A circle is a curve sketched out by a point moving in a plane. The radius of three circles will be 1 unit, 2 units, and 4 units, respectively.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.

Given that  the scale factor from each circle to the next larger circle is 1: 2. Therefore, if it is assumed that the radius of the first circle is 1 unit, then the radius of the second circle will be,

The radius of the first circle/Radius of the second circle = 1/2

The radius of the second circle = 2 × (Radius of the first circle)

The radius of the second circle = 2 × 1 unit

The radius of the second circle = 2 units

Similarly, the ratio for the radius of the second and the third circle can be written as,

The radius of the second circle / Radius of the third circle = 1/2

The radius of the third circle = 2 × (Radius of the second circle)

The radius of the third circle = 2 × 2 units

The radius of the third circle = 4 units

Hence, the radius of three circles will be 1 unit, 2 units, and 4 units, respectively.

The diver's elevation changes by 15 meters.

The diver is initially stopped at a height of 11 meters.

After that, he leaps, falling 11 meters, causing an initial elevation drop of 11 meters.

Finally, he descends to a depth of 4 meters, or 4 meters below the surface of the water, adding 4 more meters to the elevation change (11 + 4 = 15).

The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.

You may calculate the angle of elevation, for instance, by standing on the ground and looking up at the peak of a mountain. For instance, you can determine the angle of elevation by standing on the ground and gazing up at a mountain's peak.
