Find the slope of the line that passes through (2, 12) and (4, 3). Simplify your answer and write it as a proper fraction, improper fraction, or integer.

The essay will need to be in your own words of course, but the basic idea is to replace x with 0 and solve for y to get the y intercept. To get the x intercept, replace y with 0 and solve for x.

Here's an example

2x+5y = 10

Let's find the x intercept

2x+5y = 10

2x+5(0) = 10

2x = 10

x = 5 is the x intercept

Now we'll do the y intercept

2x+5y = 10

2(0)+5y = 10

5y = 10

y = 10/5

y = 2 is the y intercept

The x intercept is the location where the graph crosses the x axis. The y intercept is where the graph crosses the y axis.

N is the set of natural numbers that are factors of 20={1,2,4,5,10,20}

Factors: A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product. There are two methods of finding factors: multiplication and division.

given in the question that, N is the set of natural numbers that are factors of 20

factors of 20 are = 1,2,4,5,10,20

so the set of factors of 20 is={1,2,4,5,10,20}

Answer:

It should be (1, 2, 4 , 5, 10, 20)

The food that the former world record holder should eat per day is 0.33kg.

The first step is to determine the ratio of the smallest horse's food per day to the height of the horse. This can be determined by dividing the food eaten per day by the height of the horse.

Division is the operation used in mathematics that is used to determine the quotient of two or more numbers

Ratio of the height and food eaten per day = 0.3 / 42.5

The next step is to multiply the ratio gotten in the previous step by the height of the former world holder

Food the former holder should eat = (0.3 / 42.5) x 46.25 = 0.33 kg

The transformed function is:

g(x) = 2*|x + 1| - 6

We start with the original function f(x), and we define the transformed function as g(x).

First, we have a translation of 1 unit to the right, so we have:

g(x) = f(x - 1)

Then, we have a vertical stretch by a factor of 2.

g(x) = 2*f(x - 1)

A translation of 4 units down:

g(x) = 2*f(x - 1) - 4

And we know that f(x) = |x + 2| - 1

Replacing that, we get:

g(x) = 2*( |x -1 + 2| - 1) - 4

g(x) = 2*|x + 1| - 2 - 4

g(x) = 2*|x + 1| - 6

Answer:

lower bound for area = 140.25 square cm

upper bound for perimeter = 54 cm

======================================================

Explanation:

L = length

W = width

The unknown length L is rounded to the nearest cm to get to 17

This means it's in the interval [tex]16.5 \le L < 17.5[/tex]

The smallest it can get is L = 16.5 since that rounds to 17

It doesn't reach 17.5 since that would round to 18. But it could be L = 17.49 or L = 17.499 or L = 17.4999 and so on.

Similarly, if the unknown width W rounds to 9 cm, then its unrounded value is somewhere in the interval [tex]8.5 \le W < 9.5[/tex]

------------------------

Select the lower bounds of L and W to compute the lower bound of the area

length*width = L*W = 16.5*8.5 = 140.25

The smallest area possible is 140.25 square cm.

--------------------------

Use the upper bounds of each L and W to find the upper bound of the perimeter.

P = 2(L+W)

P = 2(17.5 + 9.5)

P = 54

In the previous example, we could have a true area of 140.25 square cm. However in this case, there's no way to reach this upper bound 54 itself. This is the so called "ceiling" which we can think of as an electric fence or asymptote value.

We could have the following example perimeter values that approach 54 but not actually reach it

and so on.

Step-by-step explanation:

have a nice evening

The boat is moving at 2  miles per hour and current is 4 miles per hour.

In calm water, the boat travels at a 2 mph pace.

4 miles per hour is the current's speed.

One such computation is as follows.

Let a be a representation of the boat's speed.

Allow b to be the current's speed.

20(a + b) = 240, according to equation 1.

Equation 2: 60(a + b)

Equation 3: a + b = 12

Equation 4: a - b Equals 4.

Equation 3 and equation 4 combined

(a + b) + (a - b)= 12+4

2x = 16

a= 16/2

a= 8

Calculate equation 4 minus equation 3

(a + b) - (a-b)= 12-4

2b= 8

b= 8/2

b= 4

As a result, the boat is moving at 2 miles per hour, while the current is moving at 4 miles per hour.

The ratio of the length of the car to the length of the model is 15 : 1.

A ratio compares values. Ratio, is a term that is used to compare two or more numbers. in a simpler terms,  a ratio shows how many times one number contains another.

Therefore, the car is 10 feet long and the model is 8 inches long.

Hence, the ratio of the length of the car to the length of the model can be calculated as follows:

10 ft = 120 inches

Hence,

120 inches : 8 inches

let's reduce it by dividing by 8

120 / 8  : 8 / 8

Step-by-step explanation:

"D" would be the correct answer. "f(x-10)" means that the "10" would be moving right-- the positive direction. Therefore, h(x) would be located 10 units RIGHT of f(x), which passes through the origin, (0,0). Statement A is correct because, on a graph, you'd have line f(x) passing through the origin, and towards the right, 10 units, (positive) you would have h(x) making them identical. So yes, same slope. Statement B is also correct, they're obviously parallel if they're beside each other. Statement C is correct as well. Although they're parallel, they don't share the same X-intercept. f(x)'s x-intercept would be (0,0), origin. h(x)'s x-intercept would be (10,0). These three statements, A,B, & C are correct statements therefore they're not our answers since we're looking for the incorrect statement....... STATEMENT D!

we know we have 75 mL of A, that means A itself since it's 10% alcohol, really only has 75 * (10/100) = 7.5 mL of alcohol, likewise the B solution has say "x" mL, so alcohol wise it only has "x" * (55/100) = 0.55x, and we have a final mixture we need of say "y" mL at 30% alcohol.

point slope form = y-(-43)=[tex]-\frac{2}{21}[/tex](x-3)

slope intercept form = -[tex]\frac{152}{7}[/tex]=c

Finding the ratio of "vertical change" to "horizontal change" between any two unique locations on a line yields the slope. Occasionally, the ratio is written as a quotient (also known as a "rise over run"), which produces the same number for every two unique points on the same line. Negative "rise" refers to a diminishing line. The line could be functional, established by a road surveyor, or depicted in a graphic that represents a road or a roof as a description or a design.

The absolute value of the slope is used to determine how steep, incline, or grade a line is. The steeper the line, the larger the absolute magnitude of the slope. A line's direction might be either horizontal, ascending, decreasing, or vertical

If a line is rising from left to right, it is increasing. Since m>0, the slope is positive.

If a line decreases from left to right, it is said to be diminishing. The slope is inverse, or m0.

A line has zero slope if it is horizontal. This function has a fixed value.

A line's slope is ambiguous if it is vertical.

Slope= [tex]\frac{x-x1}{y-y1}[/tex]= [tex]\frac{3-5}{-22+43}[/tex]=[tex]\frac{-2}{21}[/tex]

What is Divide?

Split, in its simplest form, is to divide into two or more equivalent portions, spaces, groups, or divisions. Split, in plain English, is to provide the entire item to a group in equal portions or to divide it into equal pieces. Let's say a square is divided into two triangles with equal areas by a diagonal. A division operation may or may not provide an integer as the outcome. The outcome may occasionally take the form of decimal numbers.

Divide or division is denoted by the letters, slash (/), or a horizontal line. When dealing with a variety of problems and calculations, these symbols are useful. Also, "x by y" or "x over y" might be interpreted as "x/y" or "x y."

The constant of proportionality is known as the slope of the line.In the graph constant of proportionality is 1/2

The constant of proportionality is known as the slope of the line.

Constant of proportionality is nothing but slope of a line

The formula for calculating slope is expressed as:

m = y₂-y₁/x₂-x₁

Given the coordinate points (2/3, 3/4 ) and (0,0).

y₂=0, y₁=3/4, x₂=0,x₁ =2/3

substitute the values of  y₂=0, y₁=3/4, x₂=0,x₁ =2/3 in slope formula to get constant of proportionality.

The constant of proportionality is expressed as:

m = 3/4 × 2/3

m =6/12

m=1/2
