Answer:sorry I don’t speak proeze najsztbsza but do you know the way

Step-by-step explanation:

Slope = change in Y / change in x

Slope = (-7 - 2) / (-3 - -3)

Slope = -9/0

Because the change in x = 0, the slope is undefined.

The answer is the slope is  undefined.

Answer:

therefore, to produce 1000 watches , it would cost 9000 dollars.

Price : 9 dollars a watch

Step-by-step explanation:

C=6000 + 3x

what is the cost of producing 1000 watches?

first do this

C= (1000)= 6000 + 3(1000)

C= (1000)= 6000 +3000

C= 9000

exact form: r= 9/4

decimal form: r=2.25

mixed number form: r= 2 1/4

Step-by-step explanation:

Answer:

R=2 1/4 or 9/4

Step-by-step explanation:

You make the 4 1/2  a 4/24 so it equals 2 1/4

Answer:

diagonal = = 12.8 inches (to the nearest tenth of an inch)

Step-by-step explanation:

As shown in the diagram attached to this solution:

Let the Length of the rectangular board = a

Let the width = b

Let the diagonal = d

where:

a = 10 inches

b = 8 inches

d = ?

Triangle ABC in the diagram is a right-angled triangle, therefore, applying Pythagoras theorem:

(hypotenuse)² = (Adjacent)² + (Opposite)²

d² = 10² + 8²

d² = 100 + 64

d² = 164

∴ d = √(164)

d = 12.806 inches

d = 12.8 inches (to the nearest tenth of an inch)

N:B Rounding off to the nearest tenth of an inch is the same as rounding off to 1 decimal place.

Answer:

c+d = 5/3

Step-by-step explanation:

3(c+d) = 5

Divide each side by 3

3/3(c+d) = 5/3

c+d = 5/3

Answer:

3(1+d)=5

3×1=3

3×d=3d

:3+3d-5

3d-2

3d=2 (Devide both sides by 3)

d=2/3

Answer:

f(3) =-1

Step-by-step explanation:

f(x) = x^2 - 5x + 5

Let x=3

f(3) = 3^2 -5(3) +5

      = 9 -15+5

      = -6+5

      =-1

Answer:

y>3x+2

Step-by-step explanation:

1. use y2-y1/x2-x1 to find the slope (3)

2. since the y-intercept is already give as (0,2) we have the equation y=3x+2

3. finally since the left side is shaded, that would mean everything greater than that equation can equal y therefore y>3x+2

Answer:

Step-by-step explanation:

I know know it that that girl is wrong

The polygon being described is a trapezoid, where one base is twice the length of the other base.

A quadrilateral is a four-sided polygon, having four edges and four corners

The polygon being described is a trapezoid, where one base is twice the length of the other base.

Let the shorter base be b and the longer base be 2b.

To divide the figure into two identical trapezoids, the line must pass through the midpoint of the longer base, creating two trapezoids that are mirror images of each other.

The perimeter of each trapezoid can be found as follows:

Perimeter = sum of lengths of all sides

Hence, the polygon being described is a trapezoid, where one base is twice the length of the other base.

Answer:

the answer is b. The mode of the data in dot plot 1 is less than the mode of the data in dot plot 2.

Step-by-step explanation:

In the dot plots 1 and 2, the statement which is true is that the mean of the data in dot plot 1 is greater than the mean of the data in data plot 2.

The dot plot is the way oif representation of the data. This data is plooted in the form of points or dots over an x-y axis. The dot polt is also known as the strip plot.

Dot plot 1 is the top plot. The value of it are as,

2,3,4,5,5,6,6,6,6,7,7,7,8,8,9,10

Dot plot 2 is the bottom plot. The value of it are as,

1,2,2,3,3,4,4,4,5,5,5,6,6,7,8,9

The options given in the problem are,

Range is difference between the highest and lowest value. The range of the first dot plot is,

[tex]r_1=10-2=8[/tex]

The range of the Second dot plot is,

[tex]r_2=9-1=8[/tex]

Range of dot plots are equal.

Mean of the dot plot one is 6.1875 and mean of the dot plot second is 4.625.

The median of the data in dot plot 1 is 6 and the median of the data in dot plot is 4.5. Thus they are not equal.

The mode of the data in dot plot 1 is 6 and the mode of the data in dot plot 2 is 4 and 5. Thus this is not correct option.

Hence, in the dot plots 1 and 2, the statement which is true is that the mean of the data in dot plot 1 is greater than the mean of the data in data plot 2.
