The slope of the line is 7 x - 8 y + 56 = 0  0r 8 y = 7x - 56

What does it mean by slope of a line ?

The ratio of the difference between the y- and x-coordinates of the two points that make up the line must be calculated. The slope of the line is the value that is obtained. It displays how the line's y-axis climb compares to its x-axis run.

Given : The two points are A( 0, 7 ) and B ( -8 , 0 )

The formula of the slope of the line is

y₂ - y₁ = m ( x₂ - x₁ )

And m = y₂ - y₁ / x₂ - x₁

m = - 7 / - 8 = 7/8

therefore , y - 0 = 7/8 ( x + 8 )

8 y = 7x + 56

7 x - 8 y + 56 = 0

The sum of the angles of a triangle always equals 180°, then we can formulate the following expression:

(x + 69)° + (39 + x)° + 90° = 180°

By combining like terms in the above equation, we get:

x + x + 69 + 39 + 90 = 180

2x + 198° = 180°

We can solve for x to get:

2x + 198 - 198 = 180 - 198

2x = 180 - 198

2x = -18

x = -18/2

x = -9

Then, x equals -9.

In order to calculate the measure of angle A, we just have to replace the value of x into the equation 39 + x, then we get:

mmm

Then, the measure of angle A equals 30°.

The equation of the line with the point (1, 2) with the slope - 3 will be;

⇒ y = - 3x + 5

What is Equation of line?

The equation of line with slope m and passes through the point

(x₁, y₁) defined as;

⇒ y - y₁ = m (x - x₁).

Given that;

The slope of the line = -3

The point on the line is (1, 2).

Now,

Since, The equation of the line with slope m and passes through the point (x₁, y₁) defined as;

⇒ y - y₁ = m (x - x₁).

Hence, The equation of the line with slope - 3 and passes through the point (1, 2) will be;

⇒ y - y₁ = m (x - x₁).

⇒ y - 2 =-3 (x - 1).

⇒ y - 2 = -3x + 3

⇒ y = - 3x + 3 + 2

⇒ y = - 3x + 5

Therefore, The equation of the line with the point (1, 2) with the slope - 3 will be;

⇒ y = - 3x + 5

Answer:

d = 8 , a₁ = - 6 , a₂ = 2

Step-by-step explanation:

the recursive formula is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + d

where d is the common difference

compare with

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 8

then common difference d = 8

the initial term is the first term, that is a₁ = - 6

then

a₂ = a₁ + d = - 6 + 8 = 2

A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed.

A scatter plot is a graph that displays data points linking two variables. Each item of data is represented by a separate point on the scatter plot, and the points are not linked.

In a scatter plot, a cluster is a group of dots that follow the same basic pattern. They might follow a straight route or a curved line. Many points can be found in a cluster.

A three-number total equals twenty. The third is three times as much as the second. From the equation numbers area 0.1, 1.2 and 17.4.

Given that,

A three-number total equals twenty.

The third is three times as much as the second.

11 less than 10 times the second is 9 times the first.

We have to find the numbers.

First take the 3 numbers as a,b and c

A three-number total equals twenty.

We can write as,

a+b+c=20→ equation(1)

The third is three times as much as the second.

c=12b+3→equation(2)

11 less than 10 times the second is 9 times the first.

9a=10b-11→equation(3)

Now,

From equation(3) we get,

a=(10b-11)/9=10/9b-11/9

From equation(2) we get,

c=12b+3

Substitute value a and c in equation(1),

10/9b-11/9+b+12b+3=20

10b-11+9b+108b+27=20×9

127b+16=180

127b=180-16

127b=164

b=164/127

b=1.2

Substitute the b value in equation (2) and (3)

Equation(2)

c=12b+3

c=12(1.2)+3

c=14.4+3

c=17.4

Equation(3)

a=10/9b-11/9

a=10/9(1.2)-11/9

a=1.3-1.2

a=0.1

Therefore, the numbers are 0.1, 1.2 and 17.4.

Answer:

- 3,  2/3

Step-by-step explanation:

Given:

3·x² + 7·x - 6 = 0

General Equation:

a·x² + b·x + c = 0

a = 3;

b = 7;

c = - 6.

Discriminant:

D = b² - 4·a·c = 7² - 4·3·(-6) = 49 + 72 =  121

√ (D) = √ (121) = 11

Solution:

x₁₂ = ( - b ± √(D) ) / (2·a);

x₁ = ( - 7 - 11 ) / (2·3) =  ( - 18) / 6 =  -3

x₂ = ( - 7 + 11 ) / (2·3) =  4 / 6 = 2 / 3

An object is moving at a speed of 27.3 yards per hour.

3 kilometers must first be converted to yards.

1 m =  1.09 yards.

1 Km = 1093.61

3 km to yards is  3280.84  

Currently, we must convert 5 days to hours. There are 24 hours every day, we shall multiply that number by 5 to find the number of hours in 5 days.

5 * 24 = 120 hours

To determine the speed in yards per hour, divide 3280.84 by 120.

3208.4/120

= 27.34 yards per hour

The linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet will be T = (-9/2)x +103.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that, it is 76 degrees at the 6000-foot level of a mountain and 49 degrees at the 12000-foot level of the mountain.

As we know the linear equation in the slope-intercept is found as,

y =mx + b

Replace m with the c,y with the T, and b with the k as

T = cx + k

From the given data,

76 = c(6) + k

76 = 6c + k

⇒ k = 76 - 6c

For condition 2,

49 = c(12) + k

49 = 12c + k

Substitute the value of k in the above equation,

49 = 12c + (76 - 6c)

49 = 12c + 76 - 6c

49 - 76 = 6c

6c = -27

c=-9/2

Put the value of c in the equation,

K = 76 -6c
K = 76 -6(9/2)

K = 76+27

k = 103

Put the value of c and k in the equation below,

T = cx + k

T  = (-9/2)x+103

Thus, the linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet will be T = (-9/2)x +103.

Considering the volumes of the ball and of the box, it is found that the balls will not fit into the box.

The ball is spherical, with a diameter of 8 inches = radius of 4 inches.

The volume of an sphere of radius r is given by:

V = 4/3πr³.

Hence the volume of each ball is given by:

V = 4/3π x 4³ = 267.4 cm³.

The volume of the three balls is:

V = 3 x 267.4 cm³ = 802.2 cm³.

The box is a triangular prism, hence the volume is given by the multiplication of the base area by the height, as follows:

V = Ab x h.

The height of the box is of 9 cm, however we have to find the base area.

From the bisection, at the right side of the triangle, we have that half the side of the equilateral triangle is of 7.8 cm, hence the side length is of:

s = 2 x 7.8 = 15.6 cm.

Hence, bisecting the base triangle to find the height, it will have:

Then the height can be found as follows:

tan(30º) = h/7.8 (tangent = opposite side/adjacent side)

h = 7.8 x tan(30º)

h = 4.5 cm.

The area of a triangle is half the multiplication of the side length and the height, hence the base area is:

A = 0.5 x 15.6 x 4.5 = 35.1 cm².

Then the volume of the box is:

V = 35.1 x 9 = 315.9 cm³.

The volume of the three balls is of 802.2 cm³ > 315.9 cm³, hence the three balls will not fit into the box.

The box is missing and is given by the image at the end of the answer.

Step-by-step explanation:

The option A that f(-3)=g(-4) will be the correct option for the given graph  of set of intersecting line meeting at point (-3,-4).

When two or more lines intersect in a plane, they are referred to as intersecting lines. The intersecting lines share a common point, which exists on all of them and is known as the point of intersection.

The intersecting lines (two or more) always meet at one point.

The intersecting lines may cross at any angle. This formed angle is always greater than 0° but less than 180°.

A pair of vertical angles is formed by two intersecting lines. Vertical angles are opposite angles that share a vertex (which is the point of intersection).

In the graph we can see that lines are meeting at (-3,-4) that is why the option A f(-3)=g(-4) is most suitable option.

What is a probability distribution?

Given that the number of word processors, x, purchased each year has the probability distribution.

E(X)=1* (3/10)+2*(2/5)+3*(1/5)=1.7

E(X^2)=1^2(3/10)+2^2(2/5)+3^2(1/5)=3.7

Expense=E(1200x-50x^2)=E(1200x)+E(-50x^2)=1200E(x)-50E(x^2)
