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 slope is -1

Answer:

Yes! Water is moist.

Step-by-step explanation:

Water is moist because water is a liquid.

From the dictionary:

moisture:

"water or other liquid diffused in a small quantity as vapor, within a solid, or condensed on a surface."

moisture is a type of liquid, and water can be 'diffused in a small quantity as vapor'

So, logically, water is moist.

The most appropriate choice for set will be given by -

1) Number of students who went to Nashville but not Pittsburg = 5

2) Number of children who like to use markers but not colour pencils = 2

3) Number of students who have been on TV but not in a play =2

What is a set?

Set is a well defined collection of distinct objects. The objects are called elements of the set.

Set can be empty or non empty, finite or infinite.

The number of elements in a set is known as the cardinal number of the set

Here,

1) Number of students went to Nashville = 12

Number of students went to Pittsburg = 10

Number of students went to both cities = 7

Number of students who went to Nashville but not Pittsburg = 12 - 7

                                                                                                     = 5

2) Number of children who like to use markers = 5

Number of children who like to use coloured pencils  = 10

Number of children who like to use both coloured pencils and markers          

                                                                                                           = 3

Number of children who like to use markers but not colour pencils = 5 - 3

                                                                                                                = 2

3) Number of students who like to play = 9

Number of students who like to watch TV = 7

Number of students who both like to play and watch TV = 5

Number of students who have been on TV but not in a play = 7 - 5

                                                                                                    = 2

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

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.

The value of k after eliminating the fraction in 3/5k -5 = 7/10k is 7.

To get the answer follow the given steps below:

3 / 5 k - 5 = 7 / 10 k

Step 1 => 3 (10 k) = 7 (5 k - 5)               by cross multiplying the numerator                  and denominator of both the sides.

Step 2 => 30 k = 35 k - 35                    multiplying 5 inside the brackets with 5k - 5

Step 3 => 35 = 5 k

10 is a natural number, whole number and an integer.

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. Integers may be defined as the collection of positive and negative numbers along with zero but no fractions. 10 lies in this range so 10 is an integer.

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

Step-by-step explanation:

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
