Answer:

y int = -2

slope = 1

Step-by-step explanation:

x-y=2

-y=-x+2

y=x-2

y int = -2

slope = 1

Answer:

Slope = 1

Y-intercept = -2

Step-by-step explanation:

   First, we will put it into slope-intercept form.

x - y = 2

x = y + 2

y = x - 2

   This gives us the slope of one and the y-intercept being -2.

Answer:

the number will get 1000 times larger than its original number or 3 zeroes will be added in the last place of the number

Step-by-step explanation:

let's say x=5,

if we multiply 5 by 1000 it becomes 5000 (it is 1000 times more or larger than its orignal number and 3 zeroes are added in 5000).

Answer:

(2,-3) and (49/29, -108/29)

Step-by-step explanation: Assuming this is an exam and time is limited, first you gotta sketch the circle for clarity. Using the standard circle equation

(x-a)^2 + (y-b)^2 = r^2

(x-1)^2 + (y+3)^2 =1

You can always expand to verify it gives x^2 + y^2 - 2x + 6y + 9=0

Now you know (a,b) which is also the center of the circle being= (1,-3) and the radius(r) = 1

Your first assumption here even without drawing the circle is that it has to be in the fourth quadrant meaning all values of x for any point of intersection on that circle has to be +ve. Looking at your answer choices only c with is (2,-3) and (49/29, -108/29) fulfills this hence it is your answer.

Also you have to realize point (2,-3) on the straight line has same y coordinates with center of this circle.

Answer:

Step-by-step explanation:

When a = -1   and  b = -2    U = a-b    

                                                   -1 - -2 = 1    U =1

when a = -4   and  b = 1          V = a-b =   - 4 - 1 =-5    V = -5

Using the permutation formula, as the order is important, it is found that there is a 0.000331 probability of selecting the balls in the desired order.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 4 balls will be taken from a set of 9, hence the total number of outcomes is:

[tex]P_{9,4} = \frac{9!}{5!} = 3024[/tex]

The desired outcome is only one, hence the probability is given by:

p = 1/3024 = 0.000331.

There is a 0.000331 probability of selecting the balls in the desired order.

Answer:

  not a right triangle

Step-by-step explanation:

The side lengths of a right triangle will satisfy the relation given by the Pythagorean theorem:

  c² = a² +b²

  23² = 14² +19²

  529 = 196 +361

  529 = 557 . . . . . . . . not true; not a right triangle

__

The longest side (23 mm) is too short for a right triangle, so the angle opposite will be smaller than 90°. This is an acute triangle.

answer: 18

The quadratic equation y = -x^2 - 4x - 3 has a degree of 2

The vertex of the function is (-2,1)

The equation of the function is:

y = -x^2 - 4x - 3

Differentiate

y' = -2x - 4

Set to 0

-2x - 4 = 0

Solve for x

x = -2

Substitute -2 for x in y = -x^2 - 4x - 3

y = -(2)^2 - 4(-2) - 3

y = 1

The above means that the vertex of the function is (-2,1)

Based on the information provided, the mean number of people in a class is 21 people.

To calculate the mean number, the general formula is the total of people in the class/ number of classes.

Then, let's find the total of people in classes by adding the number of people that are in class every day:

13+23+24+31+14 =  105 people in total

Number of classes: 5 classes or 5 days

The mean number of people in a class: Divide the total of people by the number of classes

105 / 5 = 21 people per class in average

Step-by-step explanation:

Find the slope of the original equation by putting it into y=mx + b form

2x+6y=-4                  Given

2x-(2x)+6y=-4-(2x)   Subtract 2x from both sides

6y= -2x -4                Simplify

6y/6= -2x/6 -4/6      Divide both sides by 6

y= -2/6 x - 4/6          Simplify

*perpendicular slopes are opposite reciprocals*

-2/6 = slope

2/6 is the opposite of -2/6

The exact answer is 7.6923076923

Answer:

Given that the area of the base is 440.4, all we would need to find out is the sum of all the areas of the triangles surrounding it.

Formula for area of a triangle:

A = BH x 1/2

Where 'B' represents the base, 'H' stands for the height, and 1/2 simply means to divide the product of those two lengths(base and height) by 2.

Plug in what we know:-

A = BH x 1/2

A = 16(20) x 1/2

A = 320 x 1/2

A = 320/2

A = 160 mm is the area of one triangle, but we want to know the area of all 5 triangles, so;

160(5)

= 800 mm is the area of all the triangles.

Now add the base area to the area of all the triangles.

440.4 + 800

= 1,240.4 mm.

Therefore the surface area of this pyramid is 1,240.4 mm.

Answer:

1240.4 mm²

Step-by-step explanation:

The surface area of a pyramid = Area of the all sides + Area of base

Each side is a triangle.

With a regular pentagonal pyramid, the area of each triangle is

A = 1/2 x base x slant height

For the 5 triangles,

A = 5 x 1/2 x base x slant height = 1/2 x 5 x slant height

Substitute values,

A = 5 x 1/2 x 16mm x 20mm = 800 mm²

Area of base = 440.4 mm²

Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²
