the sum of a number v and 6.2 is at least -4.7

We can say that the graph of 4x+5y = 3/7 is a line because it can be represented by the straight line equation.

A straight line's general equation is y = mx + c, where m is the gradient and y = c is the value at which the line intersects the y-axis. This number c is known as the y-axis intercept.

Given equation :   4x+5y = 3/7

The given equation can be written as

5y = -4x + 3/7

y = (-4/5)x + 3/35

This is a form of y = mx + c

It is a the equation of the straight line.

Therefore, we can say that the graph of 4x+5y = 3/7 is a line as it can be represented as the equation of the straight line.

In the picture, there is graph with a line. The equation of the line is

2x+y-1=0.

Given that,

In the picture, there is graph with a line.

We have to find the equation of the line in the graph.

The equation of a line can be constructed using the slope of the line and a point on the line.

The equation for a line traveling through a point (x₁,y₁) and having a slope of m is given as follows: y-y₁=m(x-x₁)

Additionally, this equation can be resolved and condensed into the equation of a line in its usual form.

Here, we have points (0,1) and (1,-1).

Slope of the line m=[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

m=(-1-1)/(1-0)

m=-2/1

m=-2

We got Slope of the line m=-2

Take point (0,1)

y-1=-2(x-0)

y-1=-2x

2x+y-1=0

Therefore, the equation of the line from the given graph is 2x+y-1=0.

For the given question,

Let the distance of ship c from the bottom of the cliff is 'a'.

Let the distance between both ships is 'b' m.

The height of the cliff is 110 m.

The angle of depression by both the ship with the top of the cliff is 48° and  57°.

The number of arrangements of the word DARWIN beginning and ending with a vowel = 48 ways

The number of letters in DARWIN = 6

The vowels are "A" and "I"

Number of vowels = 2

Number of ways of arranging the two vowels that will be at the beginning and end = 2! = 2 x 1 = 2 ways

There are 4 remaining letters after excluding the vowels

Number of ways of arranging the 4 remaining letters = 4!

Number of ways of arranging the 4 remaining letters = 4 x 3 x 2 x 1

Number of ways of arranging the 4 remaining letters = 24 ways

Therefore, the number of arrangements of the word DARWIN beginning and ending with a vowel = 2 x 24

The number of arrangements of the word DARWIN beginning and ending with a vowel = 48 ways

The solution of the inequality expression given as 12 + 4y < 32 is y < 5

An inequality expression is an expression where both sides of the expression have unequal values and they make use of any of the symbols <, >, <=, >= and !=

The inequality expression is given as

12 + 4y < 32

Subtract 12 from both sides of the inequality

So, we have the following expression

12 - 12 + 4y < 32 - 12

Evaluate the like terms in the above inequality

So, we have the following expression

4y < 20

Divide both sides of the inequality by 4

So, we have the following expression

4y/4 < 20/4

Evaluate the quotient

y < 5

Answer:

8 Gallons

Step-by-step explanation:

The question is asking you how many gallons it takes to travel 184 miles given that 138 miles took 6 gallons

You first divide 138 by 6 to find the Miles Per Gallon

138 ÷ 6 = 23
This means that each gallon was 23 miles

Now you divide 184 by 23 to find how many gallons it took to drive 184 miles.

184 ÷ 23 = 8
This means that it took 8 Gallons for Josiah to travel 184 Miles

The product of the HCF and LCM of 12 ,18,30 can be written as 1080.

The H.C.F.  can be described as the greatest factor  that can be found when expressing given two or more numbers, on the other hand the LCM can be described as the least factor that exist between a two given number.

factors of 12 are: 3, 4, 2, 6, 12.

factors of 18 are: 2, 3 , 6 9 , 18

factors of 30 are ; 2, 3, 6, 5, 10

HCF; The factor that is greatest among the factors of the numbers = 6

To calculate the LCM, we need to find to find the prime factor of the three numbers as:

Prime factor of 12 are ;  2*2*3

Prime factor of 18 are ; 2*3*3

Prime factor of 12 are ; 2*3*5

LCM is now the multiplication of the prime factors which is the highest occurrence of them in either numbers as ; 2*2*3*3*5 =180

Natural numbers may be defined as the numbers which include all the positive integers that is non-negative integers, and the numbers will be from 1 to infinity. 10 is a natural number as it lies in the range from 1 to infinity. Whole numbers may be defined as the numbers which include all the positive integers as well as zero. So, the range of whole numbers is from zero to infinity and 10 is a whole number as it lies in this range.

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. B is the b in the location where the y-intercept is located (0, b). For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.

A line's slope often indicates the steepness and direction of the line. By calculating the difference between the coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them. The letter "m" is frequently used to denote slope.

where m is the slope and y=mx+b

You can also write y =-x+7 as y=-1x +7.

Therefore, the slope is determined by the number before x.

The bridge is 895.79 feet above the river.

The length of the section of the bridge above the arch is 179.58 feet.

The underside of the bridge is in the shape of an arc.

The height of the bridge is represented by the function,

y = - 0.000475x² + 0.851x

Now, when the height will be maximum, dy/dx = 0

Therefore,

dy/dx = (d/dx)( - 0.000475x² + 0.851x )

dy/dx = - 0.00095x + 0.851 = 0

- 0.00095x + 0.851 = 0

Subtracting 0.851 from each side,

- 0.00095x = - 0.851

Dividing each side of the equation by 0.00095

x = 895.7895 feet ≈ 895.79 feet

Therefore, the maximum height of the bridge is h = 895.79 feet.

The length of the section is represented by x,

y = - 0.000475x² + 0.851x

To obtain the x-intercept, we put y = 0:

- 0.000475x² + 0.851x = 0

x ( - 0.000475x + 0.851) = 0

Therefore,

x = 0 and,

- 0.000475x + 0.851 = 0

- 0.000475x = - 0.851

x = 1791.58 feet

Area of Rectangles of the given values are 5/3inches², 20/3inches², 10/3inches² and 1 inches²

What is Area of Rectangle?

The quantity of space occupied by a flat surface with a specific shape is referred to as the area. It is calculated as a "number of" square units (square centimeters, square inches, square feet, etc.) The quantity of unit squares that can fit inside a rectangle called its area.

Since we know that,

Area of Rectangle = length x width

So, by the given values we can find the area of the following:

a) 5inch and 1/3inch

Let,

Length = 5inch

Width = 1/3inch

Since,

Area of Rectangle = length x width

                               = 5 x 1/3

                               = 5/3inches²

b) 5inch and 4/3 inch

Let,

Length = 5inch

Width = 4/3inch

Since,

Area of Rectangle = length x width

                               = 5 x 4/3

                               = 20/3inches²

c) 5/2inch and 4/3 inch

Let,

Length = 5/2inch

Width = 4/3inch

Since,

Area of Rectangle = length x width

                               = 5/2 x 4/3

                               = 5 x 2/3

                               = 10/3inches²

d) 7/6 inch and 6/7inch

Let,

Length = 7/6inch

Width = 6/7inch

Since,

Area of Rectangle = length x width

                               = 7/6 x 6/7

                               = 1 inches²
